Troubleshooting Asterisk PABX Software:

__Loop and Ground and Kewl, Oh my!

In New Zealand, Telecom uses Loop-Start on all PSTN lines except on business lines where you've explicitly requested Ground-Start (or Earth-Start as Telecom call it). So if you're using Zaptel with Asterisk set your signalling to fxsls or fxols.

Command 'showparkedcalls' already registered (or something close enough)

Remove 'res_parking.so' from /usr/libs/asterisk/modules - do NOT simply rename it - Asterisk seems to try to load ALL modules!

I get an error message "Ouch ... error while writing audio data Broken pipe" from Asterisk

This error is from mpg123, not asterisk. When asterisk dies, mpg123 complains. The error that killed * is either above that message or available using GDB if it is a segfault etc. You probably have a configuration error.

SIP callgroup feature similar to ZAP groups : Could not find information whether this is possible. See also: http://lists.digium.com/pipermail/asterisk-users/2005-May/105388.html
