(Sorry for resending. I forget to attach screen dump from Asterisk console in
the first attempt).
We are testing Asterisk (1.2.5, configured for an IP PBX) for the number of
simultaneous multiple VoIP calls supported. Whenever we increase the number of
SIP end points over 250, or the equivalent of 125 caller-callee pairs, our
testing fails. In fact, adding even one additional pair of end points over the
250 makes all end points fail. I have pasted the console diagnostics posted by
Asterisk below.
Is there any inherent limitation either in Asterisk or Linux system resources
that restricts the SIP end point count to 250? I though Asterisk is an open
source SW with no restriction on the number of SIP endpoint seats. As I could
see, my CPU has plenty of slack (idle time) left when tested with 250 SIP end
points. Hence the desire to increase the simultaneous channel capacity of
Asterisk.
If you have configured your Asterisk IP PBX to serve more than 250 SIP end
points, I would appreciate some help.
Thanks,
