Asterisk Extension Limit

Is there a limit on how many concurrent calls one extension can service?

If I put this extension in my extensions.conf file,

exten => 1,1,Answer()
exten => 1,n,MusicOnHold()
exten => 1,n,Hangup()

and I generate calls to this extension. At what point, if any, will Asterisk no longer be able to handle this?

This question stems from some testing that I have been doing. While testing, I’ve have not been able to successfully get more than 24 calls to one context-extension pair. For every port I go over 24, it causes one active port to lose audio.

Anybody have any clues?


I figured this out. It was actually being caused by the IAX trunking on my machine. For some reason when I turned trunking off, the limit went away.
