What is SIP Trunking?

SIP Trunking (Session Initiation Protocol) is a flexible, low cost alternative to ISDN.

Using SIP allows your customers to experience the benefits of a hosted solution, without removing their existing legacy telephone equipment.

SIP optimises their data connection so that they have just one line for both voice services and the internet. Put simply, it’s an evolution from a traditional phone system to one that can withstand whatever changes the future may bring.

Your customers get the benefits of a hosted voice solution on the phones they’ve already got and you benefit from getting them one step closer to the cloud.

  • Business Continuity – Never miss a call with automatic call diverts using the free Daisy Web Portal.
