Will pointing the IP of the service url for the Extension Mobility Service on the Subscriber and Publisher to there own IP's, establish extension mobility redundancy? So the phone register to the subscriber and login to the subscriber for extension mobility and if they subscriber crashes the publisher is pointing to itself? Thanks
In the past i have created a second em service with a different ip address let's say the pub and called the service em backup. If the primary server fails they can go into services from the phone and select the em backup service.
