[Freeswitch-users] freeswitch sending '481 Call Does Not Exist' in return of BYE

Wed Nov 23 11:20:34 MSK 2016

Yes this is helping
but for the 'Contact' part in BYE header

below is the 'BYE' sip block from the working call, and it also not
containing 'Contact:'
=========
2016/11/23 08:30:05.595033 UAC_IP:5060 -> PROXY_IP:5060
BYE sip:2648784 at 41.218.72.6:5060;transport=udp SIP/2.0
Via: SIP/2.0/UDP UAC_IP:5060;branch=z9hG4bK76fdsg00e0oh925na7l1cd0000g10.1

To: <sip:2648784 at PROXY_IP;user=phone>;tag=yvXByKme39FKF
CSeq: 3 BYE

Content-Length: 0

=========

To compare above block with not working one, below is the block which is
getting '481 Call Does Not Exist' from media
=========
2016/11/21 14:21:36.931816 UAC_IP:5060 -> PROXY_IP:5060
BYE sip:2648362 at MEDIA_IP:5060;transport=udp SIP/2.0

Max-Forwards: 69
Call-ID: 00bT41746142115DbcGhEfCoOni at JHM2S3.MSS.MTN.CO.ZA
CSeq: 448960898 BYE

=========

However, i find values of 'CSeq' and 'Reason' fields bit suspicious.
