[cisco-voip] 69xx SCCP 9.2.1.0 Firmware bug

[Rab]

Anyone else rolled out 9.2.1.0? 

Rolled it out on mass to a customer running CUCM8.0(3a). Now when they dial a number on their 69xx series phones and lift the receiver a message displays on the phone indicating 'maximum lines in use'. Rolled them back to previous version and they behave normally. :(

Does anybody have a recommendation for a stable firmware release on these handsets?
