SIP Trunk

SIP trunk is the modern day equivalent of a digital telephone trunk line, such as an E1 or T1 circuit or Primary Rate ISDN service (e.g. ISDN-30). Instead of buying a TDM trunk from a Telco provider and connecting it to your PBX, you can now buy a SIP trunk from an ITSP (Internet Telephony Service Provider) and connect it to your VoIP / IP PBX via your broadband Internet connection. SIP trunks use the SIP standard for signalling call setup, cleardown, etc.

The features and advantages of a SIP trunk include:

- SIP Trunking is cheaper than E1/T1 trunking or ISDN service .
- SIP trunk service can be obtained quickly, since they are essential "virtual trunks".
- With SIP Trunking there is no cost of installation, as you nwould have with an E1/T1/ISDN line.
- SIP Trunking requires no TDM interface hardware, cards or media gateway - as you need when connecting to an E1/T1/ISDN line.
- SIP Trunking can provide “Event Notification” and disaster recovery options.
- Bandwidth QoS and Security can be applied to SIP Trunks via SAFW and or MPLS.
- SIP Trunking supports on demand N-way conferencing.
- SIP Trunking can support 411 Directory Assistance (in the USA) and enhanced 911 services Access (in the USA).
- SIP Trunking can provide Directory Listing - and map an existing telephone number to your trunk/PBX/VoIP system.
- SIP Trunks support Local and Inbound Calling.
- SIP Trunking provides a platform for personalised applications and rich media services.
