[cisco-voip] softphone from data to voice domain

[Ahmed -Y]

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
