SIP Trunks
Do you have your own PBX?
SIP Trunking enables us to provide affordable local and international calling by delivering calls via any broadband Internet connection.
Unlike traditional phone companies you are not forced to order extra phone lines when you need additional inbound numbers and we terminate your outbound calls at highly competitive rates.
What is even better, unlike some companies, there are no monthly charges whatsoever for our SIP Trunks, just a £5 per channel set up fee.
