Light-Weight Directory Access Protocol (LDAP)
IP Office supports LDAP directory synchronization. This allows the telephone number Directory (names and
telephone numbers) held in IP Office to be synchronized with the information on an LDAP server (limited to
5000 entries). Although targeted for interoperation with 'Windows 2000 Server Active Directory', the feature is
sufficiently configurable to interoperate with any server that supports LDAP version 2 or higher.
Remote Access Server (RAS)
IP Office provides RAS functionality allowing external users to dial in to the local area network from modems,
telephone adaptors and routers. Several of the previously described features and services can be applied to the
dial-in users to create a powerful Remote Access Server. 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 telephone call on the company telephone bill removing
the need to process individual expense claims.
Routing Information Protocol (RIP)
RIP is a distance vector protocol that allows routers to determine the shortest route to a destination network. It
does this by measuring the number of intermediary routers that need to be traversed to reach the destination
network. If more that one route exists to the same destination the shortest route is used. If a fault occurs on
the shortest route it will be remarked as being infinite and any alternative route will become the new shortest
route. This behavior can be used to add resilience into a data network. Where a customer has an existing data
network comprising of third party routers, IP Office added to the network can provide back up using its routing
and dial-up capability. RIP enabled routers share their knowledge of the network with each other by advertising
and listening to routing table changes. IP Office Supports both the RIP I and RIP II standards.
VPN: IPSec Tunneling
IPSec tunnels allow a company to pass data between locations over unsecured IP networks such as the public
internet. The company data is secured using 3DES encryption making it unintelligible to other parties that might
be 'eaves dropping' on the traffic. Tunneling can be applied to link offices together or provide workers access to
the office over the internet. All IP Office systems support up to a total of 256K worth of encrypted traffic to
multiple locations. Initially, inter-working is supported only between IP Offices that are connected either directly
on a WAN port or via the LAN using a 3rd Party router. IPSec is optional and enabled on IP Office through a
License Key.
Note: Check with Avaya for supported scenarios and 3rd party devices.
