<div>I can't comment on Cube, but maybe another product to review, I think cisco's expressway product might do some similar things. </div>

<div>Hi Guys,<br><br></div>I have few questions and really thankful if you answer them.<br><br></div>
<div>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.<br></div>
<div><br></div>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?<br><br></div>2) I understood cube hide topology using NAPT (nat), could there be any issues by enabling nat base hiding?<br><br></div>
<div><br></div>Regards<br></div></blockquote></div><br>
