.....I'm trying to determine if there is a method of using the VPN firmware, or another, load to connect over the internet to the PBX without actually using a VPN gateway. Our intent is to use any native ability of CM to allow this connection to come in directly to a dedicated CLAN (with a firewall switched public IP).
The basic needs are for:
1.) The phone to connect to a public IP via H.323
2.) Securely authenticate
3.) Do so over a 256-bit encrytption from phone to CM
We have CM 6.0 Standard License, using 9620L and/or 4625SW sets.
Thanks in advance!!
