Hi Steven, if i implement a UC560 in the HQ and i have a branche office with 20 users. Is it possible to setup a site-to-site vpn with the UC560 and get all the 20 users/phones from the branche office registered at the UC560 without implementing a multi-site solution? Another question. Let's say I would like to connect a branche office to the HQ (UC560 in the HQ). what is the limit of users that can be in the branch office without using a multi-site solution. Is it possible to somehow use a 870, 880 series router of cisco on both locations to take care of the site-to-site vpn. This way you don't have the limitations of the UC540/560? Awaiting your answer.
