(OK - sorry for a 3rd attempt. I see that my message came up with no line
breaks in the first two attempts).
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,
