[Freeswitch-users] conferencing

[Steven Ayre]

Yes, each SIP profile is in its own thread. That processes the SIP
messages sent/received on the SIP profile. It's a relatively small
part of the call - RTP is handled in a different thread.

Some people have found on very busy servers that with a large volume
of SIP messages to process the profile's thread became a bottleneck
and adding a 2nd profile to handle some of the traffic helped. It
might help increase the CPS your server can cope with, but probably
won't make a difference to the maximum number of concurrent calls your
server can handle.

We're in receipt of the details you recently sent us. Your order
will now be processed as normal.
