Extention Mobility Large Scale

Over a large deployment of multiple sites (with SRST gateways) and possible of 2 call manager clusters is extension mobility a good deployment strategy? What are the possible issues that could arise with this type of deployment if any?

EM does not work intercluster, you would need to create a profile for same user on each cluster if he will move between offices, consider that

Re: Extention Mobility Large Scale

That's great to know but what about a single cluster? Will having all users as extension mobility cause any issues? What about in SRST mode?

in a single cluster you only need 1 profile

Q. Does Cisco Unified SRST support Extension Mobility?

A. Cisco Unified SRST routers do not support Extension Mobility. IP phones rely on the support from Cisco Unified Communications Manager for Extension Mobility support. When in SRST mode, IP phones fall back to the SRST router with whatever profile it contains (extension#, .., etc.).
