  5. BT Business SIP Trunking – SIP trunking allows businesses to use their own equipment for VoIP calls, reducing dependency on PSTN or ISDN lines. This is ideal for larger companies with complex requirements or those looking to transition away from traditional lines ahead of the 2025 ISDN switch-off.

Costs of BT business phone systems

Pricing for BT’s business phone systems varies depending on the chosen package, features, and the number of users. Below is an outline of typical costs associated with BT’s offerings:

  • BT Cloud Voice – Pricing is more customised depending on the specific requirements, with packages typically starting around £20 per user, per month. Additional features and integrations can increase monthly costs, particularly with higher call volumes.
