Hi.
I try to register an Iphone whit an CUCM 8.6.2.23900 -10, i already set the parameters on the iphone and cucm, but aren't know if this scenario es possible.
The cucm has an public ip and it's reachable from internet.
Iphone ---- ADSL ------ Internet ------ CUCM
It's possible do this or a VPN is necessary to acomplish to register with cucm.
Regards.
