Kevin,
Thanks for trying this. I'm going to begin with the idea that the bug is
on the USR end (like last time).
I did a packet trace at the time of the disconnection and saw nothing.
But "show isdn" offers this clue:
the session going up:
NL: CALL REQUEST: 64K, #2572513
NL: CALL CONNECTED B1 #2572513
NL: CALL REQUEST: 64K, #2572513
NL: CALL CONNECTED B2 #2572513
the mysterious disconnect on the second B channel:
NL: CALL CLEARED WITH CAUSE: 16 B2 #2572513
the P50 timing out and disconnecting the first B channel:
NL: CLEAR REQUEST: B1
NL: CALL CLEARED WITH CAUSE: 16 B1 #2572513
Am I correct in thinking that if the P50 were disconnecting B2, it would
say "clear request" like it does when disconnecting B1?
Also the disconnection time is within 5 seconds of 15 minutes, 10 seconds
into the call as reported by the P50's connection timer, but it's variable.
If the P50 were causing the disconnection, I'd expect to see it disconnect
closer to precisely at the same time every time (and probably at a rounder
number).
I'll try to get my ISP to try to get USR to fix it.
