Hi,
I have below call flow and would like to know the correct behavior.
UAC UAS
INVITE ----------------->
<---------------200 OK
Ack ---------------------->
Now UAS puts call on Hold
<---------------Re-Invite with send-only
attribute
200 OK ----------> recv-only
<--------------Ack
Now UAS does Un-Hold
<-------------Re-Invite* without SDP*
200 OK ----------> recv-only
<----------------Ack with SDP
In final Ack there is no SDP attribute (sendrecv or send-only). With this
call flow UAC failed to Un-Hold and continue to be on hold operation.
I would like you to share your comments which would help to understand the
correct behavior.
Regards,
Amarnath
