We have a few remote users who want IP phones setup at their homes, which can then use the internal phone system (on Asterisk).
These users currently connect to the private network over Remote Access IPSec VPN, through an ASA 5510.
My question is what IP Phone solution would be recommended? Is there some sort of IP Phone that can connect to the users PC and then speak to our private network through that PC's VPN link?
I have checked out IP phones such as the Cisco SPA525G2 which has VPN built in, howerver this appears to only offer Anyconnect VPN, and not IPSec, which would mean buying Anyconnect licenses, and im not even sure it works on a 5510...
Are there any Cisco IP phones which have built in IPSec vpn?
Thanks!
