Integrating Voip Phones And Ip Pbxs - Vidyo VidyoGateway Administrator's Manual

7. Integrating VoIP Phones and IP PBXs

At times you may want to add voice-only participant(s) into a VidyoConference through an existing
VoIP phone system. This section provides an overview of integrating VidyoGateway with VoIP
phones and IP-based PBX systems.
Each VidyoGateway supports up to 50 simultaneous voice-only connections. Additional capacity
can be achieved by clustering VidyoGateways (as described in the previous section).
The VidyoGateway supports G.711 and G.722 (narrowband and wideband) audio codecs
commonly used by VoIP systems, and the SPEEX codec used on the Vidyo side. The
VidyoGateway supports H.323 and SIP signaling as well as Vidyo's signaling format, which is
based on SIP but enhanced to enable additional capabilities.
As calls are placed in either direction, the VidyoGateway performs transcoding between codecs,
converts signaling, and enables Vidyo endpoints and VoIP phones to participate in the same
conference or point-to-point call.
For more detailed information about how to integrate VoIP phones and IP PBXs, refer to
VoIP Phones and IP PBX's with VidyoGateway
details on SIP trunk configuration using the Trixbox CE and the Cisco Unified Call Manager
(CUCM).
