<div>Hi Ahmed,</div>
<div>take a look at this brand new feature in IOS 15.3(3) CUBE Line-Side -> <a href="http://www.cisco.com/en/US/docs/ios-xml/ios/voice/cube_interop/configuration/15-mt/voi-cucm-lineside.html#concept_B31F3F64AEA44D878C4CAB283E427B35">http://www.cisco.com/en/US/docs/ios-xml/ios/voice/cube_interop/configuration/15-mt/voi-cucm-lineside.html#concept_B31F3F64AEA44D878C4CAB283E427B35</a></div>
<div><br>
</div>
<div>you may not want to go with VCS-E because standard phones are not supported – and there will probably be no support in the future. Jabber will work in the near future in addition to Telepresence Endpoints!</div>

<div>Hi Ed and Blake,<br>
<br>
</div>
<div>Thanks for your input.<br>
<br>
</div>
<div>I started thinking that CUBE is not the right solution for me. <br>
</div>
<div><br>
</div>
<div>I read about Cisco VCS expressway and still reading more now. It seems this product is an edge device specifically for video conferencing for mobile telepresence endpoints e.g. EX90, Movi. So it may partially serve the purpose. I am trying to figure out
if 1) it can terminate the Jabber and other voice only softphones like IPcommunicator etc. 2) if it provide the network hiding like cube using nat or some other techniques.<br>
<br>
</div>
<div>Blake,<br>
</div>
<div>I studied ASA as TLS and phone proxy but trying to find out if 1) they can handle large volume of calls in SP environment without having issues. 2) they supports both voice and video soft clients.<br>
</div>
<div> May i please as if you have video endpoints like movi etc that terminate on your ASAs. Secondly, how the remote users access your internal UC infrastructure: using anyconnect vpn to ASA or you are translating (nat) remote user's public address into internal
private? Finally since you are using encryption, can you please comment on user experience about voice quality, issues like delay, jitter etc?<br>
</div>
<div><br>
</div>
Thanks once again<br>
<br>
</div>
Regards<br>

ASA UC Proxy functions. We are using ASA 5550’s in HA as a UC Proxy termination point in our production corporate network. The license is a little pricy, but as it sounds like you are in a reseller/provider platform the added security by enforcing sccp encryption
could be a selling point to balance out the cost. The setup process especially for a soft phone is quite easy for end users. Not going to lie, the initial UCM/ASA setup can be a little bit of a pain, but allows you to enforce encryption at a selectable strength
(aes family) on the calls. <u></u><u></u></span></p>
