IP Office provides Remote Access Server (RAS) functionality allowing external users to dial in to the local area network from modems, phone adaptors and routers.
Several of the previously described features and services can be applied to the dial-in users to create RAS capabilities. Dial-in users can be authenticated using either PAP or CHAP. Once authenticated the DHCP server can automatically assign the user an IP address to use while connected to the LAN. Individual time profiles and firewalls can be applied to the user restricting what they have access to and when they have access. For further security and accounting ease, IP Office can automatically call a user back. This keeps the cost of the phone call on the company phone bill removing the need to process individual expense claims.
