Hi,
Do you mean the 481 won't harm the system operation? Why openser
creates 2 BYEs message instead of 1 and cause gateway to reponse 481?
From my case, my PC for testing is P3 1GHz and 384M ram. I find that
number of the RTP connection is related to CPU loading. Below data is
captured using sipp.
call: 3 / second
concurrent: 30
CPU usage: 80%
total call: 1000
unexpected message: 481
call: 4 /second
concurrent: 90
CPU usage > 90%
total call: 1000
unexpected message: 481 & 408
From the information above, CPU is the main factor of the number of
RTP session. What is the real implementation for using openser with
mediaproxy to handle over 1000 RTP concurrent session?
Below is the screen dump about worst case in 4 calls /second. Sipp
will quit with the following error
Send: failed with Address family not supported by protocol

Hello,
openser does not reply with 481 Call Leg/Transaction Does Not Exist in
any circumstances. This is created by the gateway which has no active
call matching the dialog attributes in BYE.
What do you mean by "unstable and almost hanged"? No more CPU? Memory?
No message forwarding? Any error logs?
Cheers,
Daniel
