Hi, i have a question
I have to implement a telepnony , but i have diferent networks divided by ASAs
The CUCM are in one DCLAN (inside, in ASA DC Lan) and the telephones are at (inside, in ASA Lan) LAN.
In The first instance i ll configure it with identical nat and i will not use security encription.
But when this works i will configure secure confrences.
The question is , is mandatory to use the asa pone proxy? Because my asa not have licencing proxy.

Hi,
The phone proxy feature elimiates the need to build a VPN tunnel for voice traffic. It is not mandatory to use this feature.
According to the link below
"Phone proxy delivers secure remote access without the need for a remote-access VPN device. It does so by terminating SCCP and SIP Cisco Unified IP Phone endpoints encrypted with TLS or SRTP. "
From the ASA configuration guide:
"The Cisco Phone Proxy on the adaptive security appliance bridges IP telephony between the corporate IP telephony network and the Internet in a secure manner by forcing data from remote phones on an untrusted network to be encrypted. "

Phone proxy / SSL VPN has too many requisites, and is very complicated to configure, both on CM/CME, ASA, and the phone itself.
I recommedn a regular VPN instead.

Hi,
The Phone Proxy features are useful when you are using different subnet in your network Or Specially Useful or recomended when you would like to use your phone over the internet .
Directly plugged the lan cable (internet) in the phone & Your Ip phone can communicate with your internal phones or internet phones .
Specially Recommended for the internet connectivity .
I also Implemented ASA UC PROXY Setup For My Customer .
Thanks & Regards
