[cisco-voip] UDP profile question

[James Dust]

Good afternoon all,

We are shortly going to be undertaking an upgrade on our CUCM cluster from and too the versions listed below:

Our staff logon to their phones using Extension mobility, and UDP profiles.

Once we have upgraded and the phones register will our users need to log back into their phones?

We are currently on version:

11.5.1.1

And are going too:

11.5.1 SU5



Regards

James
