Inbound SIP Call with Delayed Offer in 3PCC Mode

Hello,

I am implementing a sample UAS application which handles inbound SIP calls in 3PCC mode using HMP 4.1 on RHEL 6.

Everything works as expected when UAC sends an SDP offer in the SIP INVITE message. However, in the "delayed offer" scenario, when UAC responds with an SDP answer in the SIP ACK message, the provided SDP answer is not handed over to the application. In particular, the corresponding metaevent.extevtdatap is NULL on GCEV_SIP_ACK event.

Please find attached the corresponding log file, network capture, and SIPp scenario file, which can be used to reproduce the problem.

Thanks.
