SIP

SIP (Session Initiation Protocol) trunking is a solution which enables voice and video calls over the internet.  SIP trunks are carried over IP network instead of a traditional phone line, helping to reduce your call rates.

Are you ready for the ISDN switch off? 

BT has announced it will switch off its Integrated Services Digital Network (ISDN) by 2025, starting the process in 2020. ISDN is used by over one million UK businesses so unless you’re using a cloud-based solution such as VoIP or SIP it’s likely you are operating via ISDN.  

SIP Trunks are one of the cheaper hosted alternatives to ISDN and offer business continuity to ensure you never miss a call.  

Choosing Sip Trunk helps to reduce your costs thanks to the lower call costs, the free internal calls and lower line rentals. Plus, diverting business calls is easy allowing you to work from anywhere.
