A team of Dublin-based experts are dedicated to managing our wholesale voice services locally, who work in tandem with our 24/7 Networks Operations Centre.  We serve the needs of both Irish service providers, and international carriers who need a voice partner locally.  We understand that IP is the future for carrier voice, and we have a full offering of next generation services to help you succeed in the voice market.

Meet all your voice interconnect requirements with a leading-edge solution that provides a bridge between your network and ours.  We can meet your domestic and international carrier voice requirements with a full mix of TDM and IP-based interconnect options. We back it up with the competitive rates and unmatched reach of our national and international networks, along with the highest levels of service quality and reliability.

For local Irish service providers we can help you achieve global reach for your voice services, whilst ensuring that you benefit from competitive rates on local termination and IDD termination to help you win business profitably.
For international carriers we are the ideal partner in Ireland for termination as we have local expertise and a network that is deeply interconnected with the national incumbent and the major mobile operators, allowing us to offer great value rates and the highest levels of call quality.

Features and Benefits

Flexible and scalable – we can tailor our service to suit different business models and access technologies, allowing you to connect your network to ours in the way that best suits you – TDM, private IP or public IP.

Network reach – we are deeply interconnected in Ireland to the incumbent provider and the local mobile operators, so we can offer the highest levels of service, reliability and value for money.

Almost instant connectivity – our public IP interconnect option can be set up almost instantly without having to invest in physical connectivity – reducing your costs and your time to market.

Fraud monitoring – we take call fraud very seriously and we have a specialist team, based on the island of Ireland, who monitor all traffic that passes the BT network 24/7.  In order to help you optimise your own fraud management practises we can provide alerts when we see suspicious traffic patterns on your routes, so that you can take the necessary measures to minimise the impact to your business.

TDM Voice Interconnect – our traditional service for transmitting legacy TDM-based calls over a dedicated SDH circuit offers the highest levels of security, reliability and service quality.

Private IP Voice Interconnect – carries IP-based calls over dedicated Ethernet circuits, enabling you to scale quickly and cost-effectively without compromising on quality, security or reliability.

Public IP Voice Interconnect – uses public internet access to connect you virtually with our network, enabling you to enter new markets more quickly and cost-effectively without the need for physical interconnect circuits.
