SIP trunks use VOIP protocol to provide lines over the internet.
A telephone system is programmed to use the SIP trunks to make calls in the same way as normal lines.
We can either provide new numbers for a service or migrate your existing number to the SIP service.
Here is the main advantage :-
SIP trunks are £14.00 per month and include 5000 minutes of calls to 01, 02 and 03 numbers per trunk per month.
If you take out a contract for 3 years it will also include 2000 minutes of calls to mobiles per trunk per month.
