I am thinking it is the new switch, we have moved all the phonesys equipmnet back to the old switch and threw a patch cord between the new and old switches for now.

I am thinking it's a speed negotation problem with the new switch. Did this about an hour ago, will check back on it after it has 4 hours run time, hope thats it.

Will investigte the serial feature key with the partner next week, this is not the first time we have had license key problems. Last time it was after an upgrade, should have had the key moved then.

Will report back later, thanks for the help.
