SIP KPML to RFC 2833 Negotiation
The Oracle® Enterprise Session Border Controller removes the Allow-Event header if it contains the value KPML.
A SUBSCRIBE request is sent for each KPML event upon a successful invite.
After the SUBSCRIBE even is successful, the Oracle® Enterprise Session Border Controller will process all NOTIFY requests and respond with 200 OK messages.
The SDP-Insertion feature will be used if the Access-side does not offer a SDP in the invite and the core side does not accept an offer-less invite.
