Many of our telephone systems can be upgraded, or come with SIP Trunk capabilities as standard. A SIP trunk is an alternative telephone line service to PSTN and ISDN telephone lines. Just like a standard analogue or digital ISDN telephone line there are rental charges for the service as well as call charges.
Whilt the running costs of SIP trunks and standard analogue and ISDN telephone lines are similar the main benefits of SIP trunks are the low installation and set up charges, quick set up times and flexibility of the telephone numbers.
