Replace ISDN lines with SIP Trunks giving your business flexibility and resilience
Enjoy significant savings
By replacing expensive ISDN phone lines with an IP connection between your existing PBX and the Green Tel network.
Our flexible SIP Trunking service can deliver the benefits of Voice over IP to your existing PBX, or simply help drastically reduce your monthly line rental charges.
The internet is now being used as the primary communications infrastructure for most businesses and the natural progression is to use it to carry your inter-site voice traffic at no cost, or to replace expensive ISDN or PSTN phone lines.
Green Tel SIP Trunks are compatible with a wide range of IP phone systems but as an alternative we can SIP-enable your existing PBX by implementing a gateway solution, without having to make any changes to your hardware.
