[cisco-voip] CUBE design consideration

[Ahmed -Y]

Hi Guys,

I have few questions and really thankful if you answer them.

Currently softphones from customers registered directly with shared UC
infrastructure (cucm, unity, presence etc). Now we are planning to deploy
some kinda gateway device and softphones from customer must
register/terminate on it before reach to UC infra. This gateway device must
hide the internal network and protect any potential attacks. Any advice
please.

1) I read about cube. I provide topology hiding and protection but question
is can softphones like jabber or movi be terminated on cube and then cube
initiate separate call leg to cucm?

2) I understood cube hide topology using NAPT (nat), could there be any
issues by enabling nat base hiding?


Regards
