Proxying SIP Registrations

[Justin Ferello]

Hello,

Can someone provide any valuable reasons to proxy SIP registrations from the VCS-E to the VCS-C, or why people do this?  The only response I have heard is that people think this is more secure, if so I do not understand how.

Thanks,
Justin

Not sure I fully understand your question, but the VCSe typically proxies SIP registrations on Mobile Jabber clients then passes the FW trough the traversal connection between VCSe and c.

What Justin is referring to is where TelePresence endpoints that would typically register to the VCS-E would instead register to the VCS-C if SIP registration proxy mode was enabled.

I've heard of the same example "it's more secure", the only thing that comes to mind is trying to limit what the VCS-E has access to on the network since it's public facing, whereas the VCS-C is internal, so it can have full access to AD and other services without too much concern.
