Hi,
I have a call flow as shown below.
UAC -------------- UAS
INVITE with SDP ------->
<-------- 183 with SDP
<-------- UPDATE without SDP
<-------- 200 INVITE with SDP
200 UPDATE without SDP ------------->
Here, there is negotiation of Session Timer and Refresher in INVITE and
UPDATE transactions.
Should the refresher be decided only based on 200 INVITE in this case?
Or should we avoid sending 200 INVITE till 200 UPDATE is received?
Else any suggestion how do we handle this glare condition?
Thanks,
Jagan
