1) Upgraded to COMOS 3.7 and rebooted
2) Ran tests and left it on line for several hours. No problems
3) Powered off and swapped the modem cards to K56FLEX.
4) Powered up.
5) ISDN works fine. Analog calls are answered by dead silence.
6) SHOW MODEM shows everything working fine.
Waiting for my call back from Livingston support :-(
