A SIP trunk is a single voice call, routed over your Internet connection to your office that provides voice services to your business. Each SIP trunk has a unique direct inward dialing (DID) number which provides the connection to the public switched telephone network (PSTN). A VoIP gateway routes and translates calls between the PSTN and your internal network. Calls originating from the VoIP network will display the DID number to users on the PSTN.
Trunks are purchased according to the number of simultaneous calls that you anticipate. If you find you need more call capacity, you can simply add trunks as needed. SIP trunks are a great way to benefit from the advantages of VoIP technology using your existing in-house PBX equipment.
SIP trunks can be purchased one at a time, compared with other solutions like a T-1 circuit, that must be purchased in increments of 23 or 24 channels. The dramatic cost savings and the high voice quality of all VoIP is making SIP trunks increasingly popular with businesses. SIP trunks offer the following advantages:
