Ikechukwu Nnamani, president/CEO of Medallion Communications Limited has made outstanding contributions to the development of the telecommunications industry in Nigeria. He played pivotal roles in deploying the telephony networks of Rainbownet Limited in the cities of Enugu, Aba, Owerri, Abakiliki, Onitsha, and Nsukka, as well as deployed networks for Megatech Engineering in Kano and Startech Networks in Abuja and has handled projects for Boeing Aerospace in St Louis, Missouri, as well as United States Navy Strategic Ballistic Missiles Defense Programme for which he was awarded a United States Navy plaque for outstanding work. In this interview with hilary okeke, Nnamani spoke on a range of issues around interconnect.

Use of Interconnect Houses by Telecom Operators
Yes, telecom operators are beginning to realize and really appreciate the value and importance of interconnect houses in the industry. At least in Lagos currently, Medallion is connected with pretty much all the operators available – GSM, CDMA and fixed lines – and we are getting patronage from each of them both in receiving and sending traffic from them to other operators.
Interconnect Houses and Billing Issues
From the beginning, the main reason why interconnect houses were created was to address these issues of interconnect indebtedness, reconciliation and settlement. It is an integral part of our service offering. In Medallion for instance, there are no disputes amongst operators connected on our network. The reason is simple – as an interconnect point, you generate an independent call records which would always be used for dispute resolution and arbitration. Also, you are able to differentiate and mediate on each type of traffic that comes through your network. So, because you have the right interconnect billing infrastructure, it is easier for you to handle billing and settlement; and these are infrastructures that some of the operators may not have. That is why you find one operator claiming that his infrastructure is better and more advanced than another’s, so whatever is coming from it should be accepted. We are able to bridge that gap. At least I can speak for Medallion as interconnect clearing house – today we have no disputes on our network.
Traffic Exchange Dynamics and Interconnect House
Operator A sends calls to operator B through the interconnect point, three call records are generated for each of the call. Operator A generates a call record, which he might start counting when the trunk is seized; operator B generates his own call records which he might start counting when the call is answered. So, you notice there is going to be a difference in timing from the point of origin and point of termination; a difference in the call records between the trunk time – when the trunk is seized – and the talk time – when you actually have conversations, which should be used for accurate billing of calls. What the clearing house does is reconcile both. On Medallion’s switch for instance, we generate both the trunk time and the talk time, and what is used for billing is talk time, not trunk time. We are able to differentiate both and show them to operators in case one of them says his own time is different – whereby he is probably assuming the trunk time for his billing. What you notice most is that as long as you do not have that independent record to fall back on, which is able to record the differences between the talk and trunk time; you are going to have disputes. So, that is one of the ways we have been able to resolve disputes considering that call records bear time of call, duration of call, the numbering plans for both originating and terminating operators. That would enable you to know that “this is an MTN call going to Zoom or Starcomms.” You should also be able to differentiate when someone is just flashing from when he is actually trying to make a call. Those short duration calls should not be counted, and we are able to separate all that through billing and reconciliation. That is how we are able to prevent disputes.
Clearing Houses’ Records Final?
Not necessarily. We would not want to put it in a militant way; we would rather say that a fact is a fact. As long as you have accurate information that you can prove is accurate, then parties are obliged to honour it. Again as I said, the beauty of calls going through an interconnect point is that you have three records – originating records, terminating records and the records from the clearing house. It is hardly possible for one to see these three records different from each other, and with Medallion’s kind of interconnect platform, it becomes a lot easier to demonstrate to all the parties that the records are accurate. That has been the experience on our network. I would not say that our position or record is final, only that historically, there has been no dispute around the records that we have generated and presented to operators.
Interconnect Houses and Number Portability
We have made a presentation to the regulators that without having efficient interconnect services; number portability is not going to work. It is simple – you need independent transparent entities to handle number portability, and in Nigeria today, it is interconnect operators that have that ability and capability because we already have the links to operators, and are independent, transparent and not in competition with any entity. We have no reason not to honour a request by a subscriber to move from one network to another. I say this not from the Medallion viewpoint but from the interconnect operator class of licence point of view – the industry would be much better, the implementation of number portability would be more efficient if it is handled through the interconnect operators who already have the infrastructure on ground and the ability to offer the service efficiently. Literally, it is no different from what we are already doing; it is pretty much going to be seen as an additional class of service within the existing class of service that we offer. So, interconnect operators are fully prepared to offer number portability and we truly hope to be able to make it a seamless transition for the industry if our service is fully embraced.
Number Portability without Interconnect Houses
It is going to be chaotic! Again, if you have pair-to-pair (when operator A directly connects to operator B), and a subscriber on operator A’s network sends him a request to be migrated to operator B’s network, chances are that that request would not be honoured because the operator would not want to lose his customers, and so will do all he can to stop that subscriber. Number portability is just not going to work unless you have independent bodies handling it; the request to be ported must be handled by an independent body that is not the operator whom the subscriber wants to move from. That is the best way it is going to work, otherwise you would see anti-competition taking over; it is just going to be inefficient, requests would be delayed and denied. Ultimately, the subscriber is going to be the one to suffer and he may not have the records. It would be the subscriber’s word against the operator’s. In other parts of the world, it is never the same operator that owns the subscriber, which handles the movement of the subscriber to another network – it is always handled by independent bodies.
Legal Issues around Interconnection
Interconnect is a regulatory requirement, it is mandatory that all operators interconnect among themselves. The major reason for this is anti-competition because the regulator wants to ensure that no one dominant operator in the industry holds others to ransom. So, there is simply a regulatory requirement that all operators must interconnect with one another; and for interconnect operators, that regulatory requirement is equally paramount. Once an interconnect operator demands for interconnect, the regulation requires that that request be honoured by the operator to whom the request is made. Going beyond the regulatory requirement and looking at it from the commercial angle; using the service of an interconnect operator has a lot benefits for a telecom operator. Even if there were no regulatory requirement, any smart operator would embrace it because it helps them to reduce the cost of their operation considering the number of interconnect links that need to be put in place; resolve issues around billing disputes and reconciliation, and issues of capacity for interconnect. Any operator that fails to embrace interconnect services fully lacks knowledge about how telecoms can function efficiently. Everyone is talking about infrastructure sharing – what an interconnect operator offers you is simply a means to share your interconnect infrastructure with others in a cost effective way. At the end of the day, your savings in cost could run into hundreds of millions of Naira.
Interconnect Houses and Emerging Mobile Currency Trend
Medallion is at the forefront of the promotion of mobile banking. We currently have a number of the mobile groups trying to work with us. For mobile banking to function properly, there must be a seamless interface between the banks and the operators and that kind of interface cannot be handled on a pair-to-pair basis. The interconnect operator makes it faster for mobile banking to be implemented across the various networks. We have been at the forefront of this and we try to promote it believing that it is one of the ways to bridge the divide between the banks and the telcos. We know that there are now more telecom subscribers than account holders in the banks. So, there is a huge market and opportunity here. It is also a global trend, and Nigeria cannot be left behind. There is a huge sector of the population that is still unbanked and this sector cannot afford banking services the way they are offered today. Mobile banking focuses on driving down the cost of providing services to be able to reach the unbanked. What a company like Medallion has done is to be very active in that space and put the necessary infrastructure in place to make it happen in a cost effective way for the banks, the operators and most importantly, the subscribers. We at Medallion just play the role of a platform provider to enable mobile banking. Without an interconnect house, it means that each of the banks and operators would set up a separate link to one another, and if you do the permutation, that would be a lot of links! You should also know that banks are not operators and vice versa, so somebody has to handle that interface between both of them to ensure that they ‘speak the same language.’ Interconnect operators are needed to provide accurate reconciliation, settlement and billing. Call records have to be generated and both parties have to be convinced that the dynamics of the transactions were handled accurately.

Federal High Court has ordered the Ministry of Finance to disclose the total amount paid under the $460 million Abuja CCTV loan, the identities of local and Chinese contractors who received the funds, the status of the project’s implementation, and details relating to the N1.5 billion reportedly paid for the Code of Conduct Bureau headquarters project.

Court Orders FG to Reveal Identity of Local Contractors in $460m Abuja CCTV Project

The Socio-Economic Rights and Accountability Project (SERAP) has urged Mr. Taiwo Oyedele, the Minister of Finance and Co-ordinating Minister of the Economy to immediately disclose the identities of all local contractors, subcontractors, consultants, vendors, and other entities that benefited from the payments under the National Public Security Communication System project in Abuja, commonly referred to as the $460 million Abuja CCTV Project.

The Federal Ministry of Finance, in response to SERAP’s contempt proceedings, had recently disclosed that: “Records from the Ministry of Police Affairs indicate that while local subcontractors may have been engaged, there is an absence of detailed subcontracting records identifying specific local companies that received funds directly from the Chinese loan.”

The Ministry made the disclosure in a letter dated 15 May 2026 and signed by R. O. Omachi, permanent secretary, Federal Ministry of Finance,.

Responding, SERAP in a letter dated 23 May 2026 and signed by Kolawole Oluwadare, deputy director, said: “We are concerned that although the judgment was delivered in May 2023, the Ministry only released some information after we commenced contempt proceedings and served a Notice to show cause in January 2026.”

According to SERAP, “Nigerians still do not know exactly the names of local contractors for the project. The absence of this information raises serious concerns about record keeping, transparency and accountability, and whether the project was implemented in a manner consistent with the public interest.”

On 15 May 2023, the Federal High Court ordered the Ministry of Finance to disclose the total amount paid under the $460 million Abuja CCTV loan, the identities of local and Chinese contractors who received the funds, the status of the project’s implementation, and details relating to the N1.5 billion reportedly paid for the Code of Conduct Bureau headquarters project.

SERAP said, “The details provided amount to only partial compliance with Justice Emeka Nwite’s judgment. Key questions remain unanswered, and further clarification is needed to ensure full and effective compliance with the judgment.”

SERAP’s letter, read in part: “We would be grateful if the requested details are provided within 48 hours of the receipt and/or publication of this letter. If we have not heard from you by then, SERAP shall proceed with our contempt proceedings against the Federal Ministry of Finance for failure to fully and effectively comply with the judgment of the Federal High Court.

“SERAP appreciates the steps taken by the Ministry to provide some information concerning the Chinese loan drawdown, counterpart funding arrangements, and certain records on equipment deliveries connected with the project.

“However, there is still no explanation regarding the missing 6,035 items as part of the status of implementation of the project. It remains unclear whether the items were subsequently delivered, whether payment was made for them, whether the contractor defaulted, whether Nigeria suffered any financial loss, and whether any steps were taken to recover public funds.

“The Ministry lists items reportedly delivered in 2013. However, it has failed to clarify how many cameras were installed, if any; where they were installed; whether the cameras are currently operational; and whether the project delivered value for money.

“The inability or failure to disclose these records raises serious public interest concerns about record keeping, contract administration, and accountability for public expenditure.

“For a project financed through public borrowing—debt Nigerians continue to repay—full transparency over all beneficiaries, foreign and domestic, is essential. Nigerians have the right to know how public funds were spent, who received them, and what was delivered in return.

“Compliance with court judgments is fundamental to the rule of law and constitutional governance. Government agencies cannot selectively comply with judicial orders or release partial information while withholding records central to public accountability.”

SERAP, therefore, urged Mr Oyedele and the Federal Ministry of Finance to fully, effectively, and urgently implement the judgment of the Federal High Court ordering disclosure of information relating to the Abuja CCTV project including by:

*Publishing the names of all Nigerian companies, subcontractors, consultants, and vendors involved in the project.

*Disclosing the amount paid to each contractor or subcontractor and the nature of work performed.

*Provide details of the status of implementation of the project including by releasing the certificates of completion, and accounting for the 6,035 project items identified as undelivered.

Nigeria Civil Aviation Authority (NCAA) has placed 11 domestic airlines on its updated “No-Pay-No-Service” list over unpaid statutory charges, a move that could affect the renewal of key operational approvals, including Air Operator’s Certificates (AOC).

According to an internal memo dated May 22, 2026, the regulator directed all its directorates to suspend regulatory and administrative services to the affected carriers until they clear outstanding debts or agree on repayment terms.

The directive means that services linked to certification and oversight, such as AOC renewals, Air Transport Licences (ATL), and Airline Operating Permits (AOP), may be withheld, raising concerns over possible operational disruptions in the aviation sector.

The affected airlines include Air Peace Limited, Ibom Air, Arik Air, ValueJet, United Nigeria Airlines, Umza Air, NG Eagle, Max Air, Caverton Helicopters, Overland Airways, and Rano Air.

At the centre of the dispute is the five per cent Ticket Sales Charge and Cargo Sales Charge, which airlines collect on behalf of the NCAA to fund safety oversight, personnel training, and economic regulation in the industry.

The memo, signed by Olufemi Odukoya, director of Finance and Accounts, NCAA, and circulated to regional offices, instructed that no directorate should render services to the listed airlines without financial clearance from the finance department.

It further warned that all services remain suspended pending verification and clearance of outstanding obligations.

While the directive has sparked concerns among industry stakeholders about possible delays in regulatory processes, some affected operators say they are unaware of the order.

Banji Ola, Arik Air’s spokesperson, said the airline had no knowledge of such a directive.

“I am not aware of any such directive or report.” Ola said

Whisky Efe and Anietie Essienette, spokespersons of Air Peace and Ibom Air, respectively did not respond as of the time of filing this report.

The development has raised fresh uncertainty in the sector, with operators and passengers wary of potential disruptions if the standoff persists

Nigeria Centre for Disease Control and Prevention (NCDC) has classified the risk of Ebola Virus Disease (EVD) importation into Nigeria as high amid the ongoing outbreaks in the Democratic Republic of Congo and Uganda, though the agency confirmed that no case linked to the regional outbreak has been detected in the country.

FG Classifies Ebola Importation into Nigeria as High Risk

Dr Jide Idris, director-general of the NCDC, in a public health advisory released on Sunday, stated that the assessment followed the World Health Organization’s declaration of the outbreaks as a Public Health Emergency of International Concern (PHEIC).

According to Dr Idris, the high-risk classification was informed by increasing international travel and population movement, continued transmission in the affected countries, uncertainty surrounding the full scale of the outbreak, and the possibility of delayed detection because Ebola symptoms resemble other endemic diseases such as malaria and Lassa fever.

He, however, assured Nigerians that high-risk states, border communities, major transport hubs, and Points of Entry had already been identified as part of ongoing preparedness efforts.

Despite the risk, Dr Idris noted that the country possesses critical response capacities, including functional laboratories, trained rapid response teams, emergency operations centres, and existing viral haemorrhagic fever preparedness structures strengthened by previous successful responses to Ebola and similar outbreaks.

He also stated that the National Emergency Operations Centre had been placed on alert mode, while the National Incident Management System had also been activated to strengthen coordination, reporting, and rapid response mechanisms nationwide.

He explained that epidemiologists and rapid response teams had been placed on standby for possible deployment, while collaboration among state ministries of health, port health services, and other relevant agencies had been intensified.

According to him, surveillance activities have also been strengthened nationwide through enhanced monitoring of alerts, rumours, and unusual health events to support early detection and response.

Dr Idris said border communities and points of entry are under increased surveillance, while health workers across the country are undergoing refresher sensitisation on infection prevention and control measures, early identification of suspected cases, and proper triage procedures.

He further said that states had been advised to incorporate Ebola preparedness into their emergency response systems by designating isolation and treatment centres, assessing bed capacity, strengthening referral pathways, and ensuring the availability of logistics and essential medical supplies.

He also revealed that plans were ongoing to preposition critical response commodities such as personal protective equipment (PPEs), laboratory consumables, body bags, and emergency medical supplies in strategic locations across the country.

On laboratory readiness, Dr Idris said Nigeria currently maintains Ebola testing capacity in states with international points of entry and within the national public health laboratory network, with surge testing capability available if needed.

He said the agency has intensified public awareness campaigns and risk communication efforts aimed at combating misinformation and false claims circulating online about Ebola.

While urging Nigerians not to panic, Dr Idris advised members of the public to maintain proper hand hygiene, avoid direct contact with bodily fluids of sick persons, refrain from handling corpses of individuals who died from unexplained illnesses, and avoid bushmeat from unknown sources.

He advised travellers arriving from countries with confirmed Ebola cases to monitor their health for 21 days and immediately contact health authorities if symptoms develop.

He also urged healthcare workers to maintain a high index of suspicion for Ebola cases, strictly observe infection prevention protocols, use PPEs appropriately, and promptly report suspected cases through established channels.
