SIP Trunking

SIP trunking provides access to and from the Public Switched Telephone Network (PSTN) over the Internet Protocol (IP). Unlike in traditional telephony, where bundles of physical wires were once delivered from the service provider to a business, a SIP trunk allows a company to replace these traditional fixed PSTN lines with PSTN connectivity via a SIP trunking service provider on the Internet.

SIP trunks can offer significant cost-savings for enterprises, eliminating the need for local PSTN gateways and costly IDSN lines.

Our SIP Trunk service provides a simple, cost effective solution for business customers that want a VoIP Telephone Service for use with their SIP enabled VoIP Phone System. SIP Trunks provide a competitive solution for extra telephone lines or for adding extra DDI Capability or back-up of traditional telephone line solutions.

SIP Trunking Prices

* DDI rental is billed as a minimum call charge, so if you make or receive over £1.00 of chargable calls in a month your DDI is effectivly free.

Example Pricing

For example - the equivalent to 2 x ISDN2e Telephone lines with a block of 10 phone numbers would be 4 x SIP Trunk rental charges @ £3.00 each per month, a set up charge of £50.00 for 10 DDI Numbers plus £10.00 per month for your number block (as a minimum call spend).

Setup costs: £50.00 (10 DDI's)
Monthly costs: £22.00 (10 DDI's + 4 inbound channels)

Compared to the cost of the equivalent ISDN2e service there is a huge saving in terms of set up and rental charges as well as the benefit of low cost calls and only having to wait a few hours for your numbers to become live, instead of a few weeks wait for the installation of an ISDN2e Telephone Line.
