SIP Trunk Solutions

SIP trunking is the fastest-growing telephony service utilising your Internet connection to provide a more flexible and lower cost alternative to ISDN for voice calls across the public telephone network.

Compared to ISDN, Gamma 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.

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.
