I have seen articles explainging that the SPA525G phone supports SSL based VPN's to the UC500 do any of the other models in the 500 series support this option?

Hello allHave a customer who requires en external aerial for their UC500.  System has to sit in a solid concrete room.  Can anyone suggest an appropriate aerial that I can attach to the system to enable the wireless option to be usable on the system

Is it possible to have a wall mounted speaker that rings for external calls.  If anyone has done this what equiptment have you used and how have you configured this scenario.
