asterisk users - Dec 2003 - chan_capi 0.3 and capiinit questions

Hi there,

two questions concerning ISDN BRI, Fritz! passive and chan_capi:

1. I noticed that I run into trouble if I do a "capiinit stop" and 
"start" while Asterisk is running. Is that normal, or do I need to
twist
my configuration somehow?
Background: ISDN callers normally get a voice menu, however my box would 
accept the call, show on the CLI that it was playing the voice menu, but 
the caller would hear nothing. Restarting * did not help, instead a stop 
now plus capiinit restart solved this.

2. If I want to use one of the two B-channels as Internet dial-up backup 
in case the cable link is down, will I have to notify * that I took away 
one of the two channels? I noticed that "capi info" in the CLI will
show
"2 channels free" even if another application outside * uses on of the
two channels...

Cheers, Philipp

Hi,

1) you are doing "capiinit stop/start" while * is running?????
do you think that unloading a device driver while * is still
running is a good idea? ;-)

2) there is no (clean) way to determine if another application
is using a B channel. However you will get a "circuit-busy" 
reason back from capi, if you hack that into chan_capi / * you
might be able to recognize that the outgoing call failed because
all B channels are in use.
