Hello All,
I have strange behavior on FreeSWITCH Version 1.2.22~32bit ( 32bit) running on Red Hat Enterprise Linux Server release 5.3 (Tikanga)
I I have FS-A and FS-B FS-A originate calls to FS-B. Then FS-B answers the call and plays 10 sec music. On successfull call FS-A plays 10 sec music too(I just want to keep the call alive)
The strange thing appears when I try to load it. I succeed to get 2000+ calls with 100 CPS. But My calls are 10sec long, so I think 1000 should be the maximum number of simultaneous calls. I used wireshark to sniff and analyze the traffic. The result:
On every call I have 10 sec of call duration and then BYE is sent. But OK which should confirm the BYE is received, is missing. Then again BYE message is sent, in matter of fact it is sent several times and finally the call is destroyed.
I have checked my network bandwidth. I have tried calls without RTP traffic (using sleep dialplan app)
Is this an issue, or I missed some configuration?
I was wondering one thing when I read this: Have you tested the other edge case? What is happening with only one call? Do you get the expected result with BYE->OK? If you see the problem with one call - then it does not seem performance (or limit) related. If you do not see the problem with one call - then try increasing the call volumes in halfs. And when you see the problems scale down in halfs until you have a sweet spot. Maybe there are some obvious settings limits that I am not aware of - but the above will at least give a little more information. Regards, Claus
