Hello,
I want to measure the performance of a OpenSER (1.3.2)proxy doing digest
authentication. In my test bed I have an OpenSER proxy and two SIPp instances:
one running the server scenario (uas), and the other one a modified client
scenario to support INVITE authentication.
While testing, I have notice that there are a lot of unexpected message errors
and retransmissions when the load is relatively low (400 cps). At 400 cps, the
server nor the SIPp instances are close to saturate their corresponding
hardware resources. I have done the same test before with a similar server,
and I was able to reach at least 3,000 cps
In the error log of the uas SIPp, I can see the following error:
"Aborting call on unexpected message for Call-Id '[email protected]':
while pausing (index 6), received
'ACK sip:[email protected] SIP/2.0"
I have tested with SIPp versions 3.0 and 3.1 and I get the same behavior.
Any ideas regarding what could be causing this problem?
Thanks,
JB
