Receiving Offer SDP

When the Oracle® Enterprise Session Border Controller receives offer SDP with applicable session parameters, it uses the same session parameters in its answer SDP (if it can support the same). This is true even if the value for that session parameter differs from the available media security profile.

Consider this example: An SDES profile is applied for incoming direction for a media security policy configured with the srtcp-encrypt value set to enabled. With the use-ingress-session-params parameter set to srtcp-encrypt for the SDES profile, the Oracle® Enterprise Session Border Controller accepts the offer SDP and also sets UNENCRYPTED_SRTCP for the cryptographic attributes in its answer SDP. When the call connects, the Oracle® Enterprise Session Border Controller does not encrypt or decrypt SRTCP packets. Without the SDES profile set this way, the Oracle® Enterprise Session Border Controller would reject offer SDP if any of its cryptographic attributes showed UNENCRYPTED_SRTCP in its session parameters list.
