UC540 with remote sites

we have a UC540 at the main office, and a router 881 in a remote office. We perform a Site to Site VPN between the office and remote site in which physical phone installed.

Is this scenario possible? or need for physical phones at the remote site to register on my uc540 central office?

another scenario would be to use two ROUTERS 881 both the central office to the remote site and perform a site to site VPN, the uc540 would be found behind the router 881.


Accepted Solutions

Yes, VPN can transport traffic for any application.

Thank you for the nice rating and good luck!

Hi Daniel,

I am not sure about going forward with the UC-320 Option, unless something has changed with it I do not believe it will achieve what you want as it is not an IOS based device and may nto integrate with a UC correctly without some heavy CLI work around's on the UC-500 side.

Also Further to what Paolo has advised, you can also consider the Cisco 6900 series phones if you want a cost alternative product, which generally perform better than the SPA series for voice quality (IMHO).

At the remote site you only need an FXO gateway.

Again, get to work with a good consultant or Cisco partner, otherwise you will never end having questions but no ready answer

initially could make a vpn site to site with the SR520 router, and physical phone so you can register from remote sites, but this router is in EOL, and its replacement is the CISCO867VAE-K9, with the 881 router I can do the same scenario?

Yes. Any Cisco router can do that.

Would have no problem with physical models of phones, for example if I use the phone SPA303 or SPA502, these phones were registered through the vpn site to site in the uc540?

For best results I always recommend not to use linksys / SPA phones but only true Cisco, however these work.

In some special phone model you would recommend to place it at the remote site?

All the 79xx phones are very good.

Thank you very much for your help Paolo ...
