Re: Install Extension Mobility of two Servers for Redundance

Hi,

I'm afraid there is not much you can do about it. Extension Mobility isn't a redundant application.

At the Service URL field you specify the exactly IP address of the CallManager server where Extension Mobility is installed.

I.e. in CallManager 3.3 it looks like that

http:///emapp/EMAppServlet?device=

#DEVICENAME#

So even if your Publisher is down the service is still trying to contact it .

The follwoing URLs will help you to understand it better

CCM 3.3
