asterisk users - May 2003 - serios problem with zaptel or asterisk

Hello,

I have installed 2 *'s and i have connected both to E1, ISDN.
Both are using EuroISDN.
On both i use alaw. The distance in ping time for them is 3 ms.
I use IAX and as a codec i use alaw on that connection.
Now the problems are:

1. I get some crunches on the line, alot of them.
2. I get some hangup's, very often, and i have no idee from where that is
comming. This is my log for a disconnect

I have try to make calls in just one way with computer, and i still have
alot of noise on the line. This systems are production, so, i can't test
alot.


Any idee will be apreciated.

Well whoever is sending you a ISDN DISCONNECT message is telling you that
the destination is unreachable. Check who is doing that.
