SIP Trunks

Session Initiation Protocol (SIP) enables voice communication between your telephone system (PBX) and the telephone network to share your data connections.


Why use SIP Trunks?

SIP eliminates:

  • The need for local public switched telephone network (PSTN) gateways
  • Costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces)

SIP can offer:

  • Combining ‘voice & data packages’ can eliminate cost and lower call rates.
  • Savings on calls compared to your standard telephone bills.
    Your standard phone line is replaced by the IP network. VoIP call rates are usually lower than traditional equivalents.
  • Flexibility in how you can use your numbers.
    With SIP you can move existing or have new numbers outside of your local exchange area.
  • Lower-cost business continuity options.

You could route your VoIP calls over your existing IP network saving money on costly call-forwarding.
