Hi ,
I have a doubt in cucm 8.5 extension mobility redundancy.
I have 3 call managers in cluster.
1. X.X.X.1 - punlisher
2. X.X.X.2 - sub1
3. X.x.X.3 - sub3
i have configured CUCM X.X.X.2 (sub 1) for extension mobility URL and in exterprise parameter configuration also (service URL). all phones are subscribed this URL and users login.
my schenerio is,
if SUB1 goes down, i change enterprise parameter service URL IP to punblisher. is that enough for users to login to extension mobility?
my doubt is,
in the above schenerio,
users press services button, request will go to enterprise parameter URL> enterprise URL will check for subscribed services> and route the request to the subscribed services for the phones . but here i have subscribed only EM service which has sub1 IP address.
how user can login?
if users can login meas, how that works.
or do i need to create 2 EM service (one for SUB1 IP, another one for PUB IP) and subscribe all the phones with both the services?
so that if subscriber fails user will login another service with has publisher IP?
I have activated EM service in all call managers inthe cluster.
please clarify my doubts.
thanks
