Subject: [asterisk-users] Howto analyze concurrent ISDN channel usage

Hi,

Does anyone have a suggestion how I can analyze the concurrent usage of 
ISDN channels? A client complains about their clients sometimes getting 
a busy tone when trying to call them. I suspect they just need to add an 
additional ISDN2 line but I need some conclusive information that they 
are indeed maxing out their ISDN channels.

Thanks,
Patrick

Hi,

It may not be that you are out of channels.  I've recently tried to setup my ISDN line for use with asterisk and ran into a similar issue.  Some people could call me and others couldn't.  My asterisk box was rejecting some calls with an "Incompatible Destination" Cause code 88.  I found that some phone lines/numbers just couldn't call my isdn line.  I still haven't figured it out yet...
