SIP 3PCC (Third Party Call Control)

The IMG supports the establishment of a session by a third party "controller" such as an application server or a Session Border Controller (SBC) allowing the IMG to integrate with services like auto attendant, conferencing, and unified messaging.


Delayed Media:

The Dialogic platform supports delayed media to allow interworking with third party call control applications (3PCC) in accordance with RFC 3725. Delayed media is implemented for inbound calls. The IMG accepts INVITE and RE-INVITE messages with or without SDP or with a held SDP. The IMG accepts SDP in the SIP ACK message.
