[asterisk-users] Dahdi & Congestion status

[Benoit]

Hi,

I'm using an half T1 line on a asterisk (obviously :)) 1.6.2.4 system,
up to recently everything
was fine but we are starting to experience the call limitation of the
line (15).

So as to warn user of the problem i attached a vocal notification to the
CONGESTION status after a Dial(),
but it looks like it also catch other congestion case (maybe on the
receiver side).

Should i / Could i use the ChanIsAvail() on a Dahdi channel ? will it
work better to detect a full group ?

regards
