[asterisk-doc] Asterisk error codes

[KOWALSKI]

Hello,

Currently, I work on a project about Elastix and implement some bash 
monitoring scripts for watching asterisk and sip trunk activities. I've 
looked for asterisk error codes on many websites concerning VoIP 
(VoIP-info.org or digium) but could not find an answer. Do you may have 
some documentation or list of asterisk existing error codes? It would be 
very nice.

Thank in advance

Michel
