I am troubleshooting a second B channel of an ISDN connection with the following debug...complaining about an "invalid call reference".
A "show isdn status" shows "MULTIPLE_FRAME_ESTABLISHED" on both channels and everything looks good with the spids,etc.
I've checked the debug on the calling party, and it never receives the "CONNECT" message sent by the called party, but rather it gets the message that the called party is not responding. I assume this is the ISDN switch telling me something.
The first B channel connects, so I don't think it's my router...any thoughts?
