Problem: Unable to perform attended transfer to external FreeSWITCH on first attempt. Subsequent attempt succeeds. Observation: On first attended transfer attempt FreeSWITCH does not receive a REFER request from sipXecs. On second attempt FreeSWITCH DOES receive a REFER request from sipXecs. In that JIRA issue I have attached the snapshot and the FreeSWITCH log as well as FreeSWITCH SIP configuration. Here is the call scenario: 7002 calls 7001 7001 starts an attended xfer to 3500 (3500 is valet parking on FreeSWITCH install) FreeSWITCH plays back the parking slot information and then proceeds to play MoH 7001 completes attended transfer but the transfer fails and the call is placed on hold. NOTE HOW SIPX NEVER SENDS A REFER TO FREESWITCH, ONLY UPDATE 7001 resumes the call and again starts the attended transfer to 3500 FreeSWITCH plays back the parking slot information and then proceeds to play MoH 7001 completes the attended transfer. This time it works. NOTCIE HOW SIPX NOW SENDS A REFER 7006 dials 3501 (the parking slot the valet module parked the call in) and retrieves the call from park.
