SIP usually fares much better than RTP and I would expect you to see
problems with the RTP streams before seeing issues with SIP traffic. Have
you verified the "voice" quality at high call rates? Are you actaully able
to push the limits without dropping packets?
I assume that you have seen:
Of particular intereset is bandwidth calculator. What can you actually
expect (best case) with you current setup (LAN, codec etc).
And if you are still running 32 bit is suggest that you are running on
older hardware. As you can see from:
You should be able to push 250 calls with 20 CPS with 15% CPU on an EC2
instance with (2,4 Ghz and 4 GB RAM).
I do not have enough experience pushing over the hardware limits so I do
not know what to expect of Freeswitch. Proper stress testing is hard
enough in itself. But my immediate reactions was that I am
very surprised that you are not seeing anything in the Freeswitch log on
the offending server not sending the final OK. If you are pushing over
some limits you would normally see something.
My first bet would be to turn up logging in sofia:
Try comparing the log output for a successfull call with a tainted call
I would be very very surprised if this turns out to be a bug where
Freeswitch silently drops actions without having logged it anywhere. With
the info supplied so far it sounds more like a setup issue.
