    What is a SIP Trunk?

    SIP stands for Session Initiation Protocol and is a protocol used for controlling communication from a phone system.
    In simple terms a SIP trunk allows you to send both voice and video calls via your broadband connection. SIP Trunking is set to replace analogue and ISDN lines as the standard in the UK, with PSTN and ISDN networks due to be switched off in 2025.

    SIP Trunks

    Easily scalable, flexible and affordable

    SIP Trunking enables voice communication between your on-premises or cloud telephone system. SIP trunks can easily be scaled up or down in number of lines depending on your business needs.


    SIP Trunks are extremely flexible and can save your business a significant amount of money on line rental and call charges.
