You can integrate your corporate SIP PBX into TrueConf Server via the built-in multi-protocol gateway. This guide will show you how to connect TrueConf Server with an Asterisk PBX (FreePBX 15 GUI).
Thanks to integrated gateway, TrueConf Server can receive external calls over the most popular SIP and H.323 telephony protocols, which allows regular telephone subscribers to call users and conferences on TrueConf Server.
TrueConf Server can be integrated with hardware video conferencing endpoints, PBXes (e.g. Asterisk) and VoIP devices using TrueConf Server built-in SIP/H.323 gateway.
