IWF Codec Negotiation H.323 Slow Start to SIP
For instances when the Oracle Communications Session Border Controller is translating a call initiated in H.323 slow start to SIP, you can enable a setting in the IWF configuration that prevents the sending an SDP offer in the SIP INVITE. Instead, the Oracle Communications Session Border Controller expects to see an SDP offer from the SIP endpoint in a provisional or reliable/provisional 200 OK, and then sends an answer in an ACK or PRACK.
With this parameter disabled (default), the Oracle Communications Session Border Controller populates the SIP INVITE with SDP based on the media profiles applied to the ingress H.323 session agent or the IWF configuration.
