Welcome to the SIP Trunking Network, Ingate's educational resource for SIP trunking information. This Web portal will aggregate knowledge from IP-PBX vendors, SIP trunking service providers and independent enterprise-focused sources, as well as Ingate Systems in an industry-wide effort to provide everything enterprises need to know to ease deployments of SIP trunking.

SIPtrunk.org is also a place where you can connect with users and even vendors to discuss your own perspectives, obtain or share information.

We invite you to browse through the site and actively participate. Your comments are welcome, please send me an email!

Sincerely,

Anders Eriksson
Chief Executive Officer Ingate Systems

Once again Ingate together with Avaya, TMC and other leading IP-PBX vendors and SIP Trunking service providers sponsored the SIP Trunking seminars at the IT Expo East in Los Angeles, Sept 16-18, 2008.
All presentations that were given during the seminars can be downloaded from the Ingate website: www.ingate.com/SIP_Trunking_seminar_fall08.php

A SIP trunk is a service offered by an ITSP (Internet Telephony Service Provider) that permits businesses that have a PBX installed to use Voice-over-IP (VoIP) also outside the enterprise network by using the same connection as the Internet connection.
