asterisk users - Jun 2007 - how can qualify=yes trigger some external event?

Hi all,

The option qualify=yes allows Asterisk to check if it can reach the 
peer. If the device does not answer within the time-out period, Asterisk 
considers the device off-line for future calls.
Is it possible to use this feature to trigger some external event, in 
case of failed reply from the peer that is tried to be reached? How can 
that be done?

Regards,
Ricardo.

Hi, Ricardo.

Currently there is no way to do this in a pure "configuration-only"
sort
of way.  However, if you're even moderately adept at C a cursory glance
through chan_sip.c will show that it would be quite straightforward to
modify the code in order to allow this.
