[cisco-voip] softphone from data to voice domain

[Brian Meade (brmeade)]

I've done this before with Acme/Sipera SBCs with all SIP endpoints.  You may be able to do this with CUBE as well (never set it up before using CUBE).  Not really going to work for SCCP endpoints unless you use Phone Proxy which only is supported in CUCM 7.x and below.  You might just be able to handle it using an ASA and Anyconnect so everyone has to VPN in first.

Subject: [cisco-voip] softphone from data to voice domain

Hi Guys,
We have a big voice domain and hundreds of deskphone share the same domain and registers with shared UC infrastructure (cucm cluster, presence, unity etc).
Currently not many users using softphone but lots of users requesting this facility. Since softphones are in data domain and i believe its not a good  practice to mix data with voice so I am thinking to place some kind of gateway in the between data and voice that not phone protect voice domain from data but also hide the topology. May be Cisco ASA as phone proxy but i am not sure if it is practical to use them for thousands of softphones. Moreover i doubt if ASA can provide topology hiding when user can have CIPC, jabber or movi.
I read about CUBE but i am still confused if cube really fit in my situation and purpose i want to achieve.
Please share your thought. In short i want to know how service providers (provides UC shared services) keep voice and data separate while provide the softphone facility to user.
Regards
