[asterisk-users] Return codes

[Doug Crompton]

How does one process a return code in Asterisk?

Example...

exten => s,n,Playback(/tmp/podcast/${CALLERIDNUM})
exten => s,n,System(rm "/tmp/podcast/${CALLERIDNUM}.gsm")


If the caller hangs up on the playback command the file remove System
statement after it never gets executed. The playback command returns a -1
in this case and logs a warning. The only thing mentioned in the command
reference is 101 for file not found.
