You can use media rules to define RTP media packet parameters, such as prioritizing encryption techniques and packet encryption techniques. Together, these media-related parameters define a strict profile that is associated with other SIP-specific policies. You can also define how Avaya SBC must handle media packets that adhere to the set parameters.

When deploying Avaya SBC with Teams, you must configure Avaya SBC media inter-working rules towards the PSTN and the Teams SIP proxy. Media inter-working is administered to support SRTP cryptography, SRTCP, and the codec priority list. Default lifetime rules are used.
