IWF Codec Negotiation H.323 Slow Start to SIP

For instances when the Oracle® Enterprise 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® Enterprise 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® Enterprise 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.
