Remote VPN IP phone provides access without incremental toll charges, Call Manager access, and IP telephony features at the expense of unpredictable voice quality and a complex deployment. To support the VPN phone, Version 8.1 also introduces two VPN Concentrators capable of supporting up to 100 calls through VPN tunnels. VPN Concentrators: IPSec vs SSL I remember the days when you could set up dial-up modems and have users connect to your NT 4.0 Server using Remote Access Service (RAS). Combining multiple modems the concentrators also share a “virtual IP address.” VIRTUAL IP The virtual IP address (vIP) is an IP address shared by both the primary and warm spare VPN concentrators. VPN traffic is sent to the vIP rather than the physical IP address of the individual concentrators. The primary and warm The ShoreTel VPN Concentrator securely connects remote IP phones to the rest of the system, enabling IT staff to implement a very secure and flexible remote work policy. Remote users simply connect a ShoreTel IP phone to a broadband router, and with minimal configuration establish a secure tunnel to the ShoreTel VPN Concentrator.
