SIP Trunks

Our SIP trunks allow you to keep costs down whilst increasing telephony resilience and flexibility. 

SIP Trunks are designed to enable existing on premise telephone systems to make VoIP calls where upgrading to a cloud telephone system is not an option.

SIP Trunks Features & Benefits

  • Route calls over the internet instead of the Public Switched Telephone Network
    Save on your phone bill with inclusive UK landline and UK mobile calls on a 36 month contract

  • Replace ISDN lines with channels connected to an IP (Internet Protocol) network
    A SIP trunk is typically 30-50% of the monthly rental of an ISDN channel
