[cisco-voip] Extension Mobility

[Rami AlHasan]

In IPCC Express Edition, usually I found extension mobility feature
enabled. and this means that extension number changes with the logged
agent. All SKINNY protocol messages changes with the new extension
number and no reference in the SKINNY messages to the original
extension number.

Is there any method to know the original number before the agent
loggin to the phone? I tried to check the CRS database for such
realtime information and found the some table that maps extension
number to agent number, but these two fields were filled with the same
value which is the agent ID or the new extension number after the
login process.

So please does anybody have any idea about getting this information
the original extension number.

Thanks.
