SIP Trunks

What are SIP Trunks?

SIP Trunks provide access to and from the Public Switched Telephone Network (PSTN) over the IP Network (Internet Protocol). Businesses use SIP Trunks to provide cost effective telephone service to their offices through a PBX or individual users in remote locations. It also can enable a business to move existing number ranges to an out of area location.

Why use our SIP Service?

1. Low cost rental. The cost of the complete service, including core IP circuit, SIP trunk and numbering is up to 50% less than ISDN30e, typically saving £1000 per annum.

2. ISDN call quality. Our circuits are provided over dedicated Dot IT 1:1 SDSL circuits and/or SIP specific ADSL2+. As these circuits are connected directly into our core network, using the G.711 codec, Dot IT can guarantee ISDN quality calls.

3. Reduced and free call charges. Our SIP trunking call charges are very good value, largely undercutting our major competitors, whilst calls between sites are free.

4. Flexible number portability and number selection. Port BT numbers onto the service and choose numbers from any UK exchange, giving much greater choice to customers as well as ensuring that they can keep their existing numbers when they move.

5. Resilience. We can protect against a circuit or system failure by providing low cost back-up circuits and an auto-divert facility to conventional telephone lines or mobiles.

6. Ease of roll-out and support. You do not need to consider whether your customer’s Internet circuit will be of sufficient quality and you will not have problems proving where faults lie as we will always provide a new, dedicated IP circuit which connects directly into our network (rather than via the Internet or a peering arrangement, both of which can lead to call quality issues).

7. Security. Dot IT’s SIP Trunks are locked down by CLI and IP address and have been designed with security built-in rather than added-on. This helps protect you and your customers from the risk of fraud.
