After much playing and getting nowhere, I was on the phone to the guys from www.voipshop.com.au and mentioned that the pri dropout problem was occuring and if they had any solutions. Immediately they mentioned something that causes a problem in australia. On longdistance phone calls (sometimes) you hear a series of short beeps that indicates to the receiver that it's a long distance call. Few calls seem to do this these days but some do. It seems to be exactly what the busy detect code looks for. On removing the busydetect (or rather setting it to 0) it solved our dropout problems. Just thought I would let everyone know incase it's an issue for anyone else. Regards Kevin
Hi Kevin Yes you shouldn't need the busy detect in there for digital systems. Busydetect is only really useful on analog systems which can't detect incoming hangup.

AFAIK, busydetect is only applicable to analog FXO ports. PRI doesn't depend on call progress tones, everything is in the D-channel. Can anyone else confirm that busydetect is used for PRI in chan_zap? If so, I would consider it a bug. Cheers. Leo
