SIP trunking
Save costs with SIP trunking with Vodafone Business by transforming physical phone lines to virtual lines.
Switch to SIP with confidence
Vodafone SIP is a Voice over Internet Protocol (VoIP) solution, turning physical phones lines into virtual lines using an internet connection.
The traditional network will be switched off in 2025, and BT no longer offers ISDN. Vodafone SIP trunking simplifies your fixed voice and data services, giving you greater control, cost savings and makes you fully prepared so you can keep on calling.
