A SIP trunk allows you to make & receive calls through our service whilst benefitting from our extremely affordable call costs & calling packages.
If you're already running an IP PBX, a SIP trunk from Dial 9 could save you money. We can provide you with a trunk which can handle any number of concurrent calls over your internet connection.
Prices start from just £20/month for 5 concurrent calls. To discuss SIP trunking with us, please contact us and we’ll be happy to talk through the options.
