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 < [02 01 3a 36 08 02 97 b5 45 08 02 c0 83 ] < Informational frame: < SAPI: 00 C/R: 1 EA: 0 < TEI: 000 EA: 1 < N(S): 029 0: 0 < N(R): 027 P: 0 < 9 bytes of data -- ACKing all packets from 26 to (but not including) 27 -- Something left to transmit (27), restarting T200 counter < Protocol Discriminator: Q.931 (8) len=9 < Call Ref: len= 2 (reference 38837/0x97B5) (Terminator) < Message type: DISCONNECT (69) < Cause (len= 2) [ Ext: 1 Coding: National standard (2) 0: 0 Location: User (0) < Ext: 1 Cause: No route to destination (3), class Normal Event (0) ] 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. Diana Cionoiu

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