SIP Trunking:  The cost effective and flexible alternative to ISDN


SIP trunking is the fastest-growing telephony service and Nomis provides one of the UK’s leading SIP trunk solutions. It connects your site directly into our partner’s network via an IP connection to carry and terminate your inbound and outbound voice calls across the public telephone network.


Nomis SIP Trunks provide a highly-flexible alternative to ISDN and are compatible with all the leading IP PBX brands in the UK market, giving you peace of mind that your PBX hardware works with the network service.  Compared to ISDN, Nomis SIP Trunks are cheaper on a per-channel basis and more flexible in terms of what telephone numbers you can have and the locations in which you can have them. In addition, they are quicker to install and offer a robust business continuity service that ensures your business never loses any calls.


Our service can support connections ranging from two channels for businesses with small PBXs, with no limit on the number of channels that can be supported for large enterprises and contact centres.
