in my test sip proxy parallel forks the invite to two contacts and two
rtpengine-offers are made with these kind of call-id and via-branch
params:
"call-id": "f33a7e21c57edbf3", "via-branch":
"z9hG4bK79d6.d19587ffadd9f72bca61d9578eb12bd9.0"
"call-id": "f33a7e21c57edbf3", "via-branch":
"z9hG4bK79d6.d19587ffadd9f72bca61d9578eb12bd9.1",
then the via-branch .0 callee answers and rtpengine-answer is sent to
with this kind of call-id and via-branch params:
"call-id": "f33a7e21c57edbf3", "via-branch":
"z9hG4bK79d6.d19587ffadd9f72bca61d9578eb12bd9.0",
after that sip proxy deletes the other branch by sending
rtpengine-delete with this kind of params:
Nov 27 02:25:55 lohi rtpengine[3792]: [f33a7e21c57edbf3] Received command
'delete' from 127.0.0.1:40700
Nov 27 02:25:55 lohi rtpengine[3792]: [f33a7e21c57edbf3] Dump for 'delete' from

"127.0.0.1" ], "from-tag": "3322319973f3909e", "command": "delete" }
and rtpengine responds:

"ok" }
which then results in deletion of the whole call, i.e., also the branch
that answered.
question: why does rtpengine not do what it is asked to do in
rtpengine-delete, i,e. delete
the offer corresponding to "call-id": "f33a7e21c57edbf3", "via-branch":
"z9hG4bK79d6.d19587ffadd9f72bca61d9578eb12bd9.1"?
