Description (partial)

Symptom:
8841 or other 88XX phone model that doesn't support a Key Expansion Module will show "Unprovisioned" or "Telephony Service Unavailable" and fail to register to Unified Communications Manager (UCM).

Conditions:
This issue only occurs if the Phone Button Template assigned to the device in UCM has more than 5 lines assigned to it.  The 8841 and 8811 phones only support a maximum of 5 lines and will reject the xml configuration file from UCM if more than 5 lines are present.
