We have a small office that recenly implemented a UC540 and all 7975g IP Phones. What I am wondering is this, is it possible to configure these phones to run as a VPN phone so we can have a couple at other small location offices we have with what we currently have or do we need to purchase something else?
I have noticed we have the "Cisco Unified Communications Manager Express" editon installed on the UC540 at the moment and logging in to that doesnt give me any VPN confguration details and I believe on the SPA525 phones are configurable usng the SSL anyconnect within the CCA software.
From what I can tell i dont believe the 7975 has the SSL VPN embedded with the phone. Can you install this feature?
I notice you can't configure the VPN from the CME gui as it seems to be only an express version with the uc540. Also i believe i have read that if you configure the uc500 range from the CLI it voids your support from the TAC.
