Session Initiation Protocol (SIP) Trunk
SIP trunk is a Voice Over Internet Protocol (VoIP) solution which connects to your existing PBX (Private Branch Exchange) using either an IP card or IP gateway converter.
Connection from your site (or sites) to our network is via an IP connection (for example broadband or Ethernet) and is delivered as an end to end service with availability, voice channel, and voice quality of service guarantees.
Numbers anywhere: SIP removes geographic boundaries so you could, for instance, have a London number that rings directly in Oxford without expensive call divert charges and you can take your business number with you wherever you relocate in the UK.
Instant divert: Instantly divert every number or direct line to a different destination as part of your business continuity plan.
Flexibility: Increase or decrease the number of SIP lines you have within minutes, ideal if you have a workforce that grows or shrinks or if you use seasonal staff.
Cost: Save up to 50% on line rental and reduce your call costs by paying monthly with SIP.
