IP-Specific Parameters
9.2.11 IPSET_MEDIA_STATE
Table 53 shows the parameter IDs in the IPSET_MEDIA_STATE parameter set. These parameters
dispatched to the application in GCEV_EXTENSION events of type IPEXTID_MEDIAINFO. In
all cases where the parameter data is an IP_CAPABILITY structure, the structure contains the
coder capabilities that were negotiated with the remote peer.
This parameter set is not supported in the SIP third party call control (3PCC) operating mode.
