SIP Trunking

Increase your call capacity and the number of concurrent calls that you can make and receive through your internet connection.

What is SIP Trunking?

SIP trunks are the equivalent of telephone lines for a VoIP system, utilising one internet connection to make and receive concurrent calls. The main difference over ISDN lines is that no physical or additional infrastructure is required when setting up SIP trunks. Bringing savings of over 60% compared to existing line rental charges, DrayTEL SIP trunking is the fast and reliable alternative to ISDN lines.
