I believe that you need to analyze the packets at your provider site. They should be able to do that. Is your HDLC located on your location or on your provider. This test should be done where Asterisk is running, because is where the problem is reported.
Start to look for Line Analyzers for HDLC, in order to check BER. If BER is high enough, then the problem is internal on your server.

Each has a TE405P and 2 PRIs. One server was experiencing crackly audio on one circuit, accompanied by HDLC bad FCS messages. The telco recabled and moved me to another port on the DMS-100. The audio is better, but there are still bad FCS problems on the span. I have moved the PRI in question to the other server, and the problem does indeed move with the circuit. There are no zaptel timing/interrupt problems present on either server. The fact that 3 PRIs are error free and that the problem moves with the circuit tells me that there is still a problem on the circuit. The telco believes that there is nothing more that they can do (provision a complete new circuit?). I don't get HDLC aborts, so the problem may not be _that_ serious. Does anyone have any comments? Would a newer (unstable) version of Zaptel drivers help? Would line-build-out parameter in zaptel.conf make any difference? _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
