Optional AVP Creation

When the get-bw-from-sdp option is configured in the sip-config, the following occurs:

When SDP contains the

b=AS:

parameter with valid value, the Oracle Communications Session Border Controller multiplies that value ×1000 and inserts the result in the Max-Requested-Bandwidth-UL and Max-Requested-Bandwidth-DL AVPs in an AAR message.

If there is no b=AS: line in the SDP, the value is taken from the media-profile, average-rate-limit parameter multiplied ×8 to get a bps value then inserted into the Max-Requested-Bandwidth-UL and Max-Requested-Bandwidth-DL AVPs in an AAR message.

The Oracle Communications Session Border Controller uses the b=AS: line (or chosen codec via the media-profile) from the final answer SDP for the session as the value for creation of these two AVPs.
