SIP Gateways

Our SIP Gateway is a simple solution that enables a PBX equipped with ISDN lines to interface with SIP trunks.

The announcement by BT Group stating that Openreach intends to migrate all customers onto the IP network by 2025 means that thousands of UK businesses with conventional PBX systems face the prospect of their phone systems becoming redundant. The SIP Gateway solution provides a simple and easy way to convert a conventional PBX system to interface with SIP trunks for VoIP telephony, future proofing customer investment in PBX hardware.

The SIP Gateway is offered on a monthly rental basis, in conjunction with Spitfire. Possible cost savings made by using SIP trunks, as opposed to ISDN circuits, should more than cover the rental for most businesses. SIP Gateways can enable a phased migration to a totally VoIP solution as well as protecting the customer's investment in their PBX system, whilst providing the additional benefits of SIP connectivity, such as increased flexibility & reduced call charges.

Switching to SIP trunks using SIP Gateway can produce significant cost savings. As an example, for eight channels of ISDN 2e savings range from 15 to 34 percent and for ISDN30 on 30 channels savings of between 35 to 58 percent are possible.
