> I'm not sure if this is a bug or a legitimate limitations. Looking at the code, I'm not really sure. Following some issues of a customer and some toying I noticed that whereas it's OK to have a context with arbitrary number of includes (and have its content be properly reported via 'dialplan show exten-foo at context-bar') I fail to originate a call from such an extension.
> I created a script to generate a context with arbitrary number of includes. It will be attached to the bug report. For example, here is the output of the script for two extensions:
> {code}
> [context-no-1]
> exten => exten-no-1,1,Answer()
> [context-no-2]
> exten => exten-no-2,1,Answer()
> [context-all]
> include => context-no-1
> include => context-no-2
> {code}
> I #include-d the output of that script into extensions.conf, reloaded the dialplan, and tried:
> {code}
> asterisk -rx 'dialplan originate Local/exten-no-NN at context-all application Wait'
> {code}
> If I generated a context larger than 127 extensions, I started getting the error message:
> {code}
> WARNING[15164][C-0000000a]: pbx.c:2461 pbx_find_extension: Maximum PBX stack exceeded
> {code}
> one for each include beyond 127. Furthermore, if the number (NN) I try is beyond 127, I fail to originate the channel.
> Looking at the code, I'm not completely sure if this is indeed how it is supposed to work. Are all includes supposed to be on the stack?
> And anyway, the error message is confusing. Maybe: "Maximum PBX stack exceeded. Too many includes while looking for $exten@$context"?
