[cisco-voip] Subject: IP phones in Disaster Recovery Site

BAT + Phone migration looks interesting but with several limitations.

Extract from CUCM System Guide

The Phone Migration window allows you to migrate feature, user, and line 
configuration for a phone to a different phone. You can migrate data to a 
different phone model or to the same phone model that runs a different 
protocol. 
...

Before you can migrate phone configuration to a new phone, consider the 
following information:
- The new phone uses the same existing database record as the original phone, 
so migrating the phone configuration to the new phone removes the 
configuration for the original phone from Cisco Unified Communications 
Manager Administration/the Cisco Unified Communications Manager database
- Before you migrate the phone configuration to a new phone, ensure that you 
have enough device license units for the new phone
...


Questions:

- different phone model or different protocol 
  I wonder if this is a hard requirement. Can we use it to migrate from a SCCP 
7962 to another SCCP 7962 if the first phone is dead?

- "ensure that you have enough device license units for the new phone"
  This one is tricky... Imagine that Autoregistration is disabled, if the new phone 
uses the same existing database record as the original phone I don't see why 
we need additional DLU's. The new phone would register and the old one will 
get rejected. That works only if it's a simple swap of the MAC address in the 
Database.


Has anyone used this and wants to share his experience ?

Any other ideas are welcomed.

Thanks
Ovidiu
