LAKE OfficeLink Communications Server


The IP – Link Communication’s Server is build upon industry standard SIP Protocols (RFC 3261) and is delivered pre-configured to the customer running on a Windows XP Server. This Server may operate in a standalone mode to host connectivity to 1,000’s of OfficeLink systems using SIP.

Communications Server overview
• Compliant with SIP standard (RFC 3261) and supporting all SIP methods and status codes.
• Built-in Web server for easy configuration and remote access from any browser.
• Unlimited number of routing entries
• Dial plan simulation. Enter a phone number in the Web interface and see where it would go
• Strict security using digest authentication and administrative protection of all configuration pages.
• Real-time information about registered devices (e.g., phones) on the registration status Web page.
• Real-time server status - status of all destination servers on the server status Web page.

Features and Specifications
SIP Features
• SIP Proxy is RFC 3261 compliant. RFC 3261 is the latest IETF RFC for Session Initiation Protocol.
• Supports all SIP methods including SUBSCRIBE, NOTIFY, REFER, UPDATE.
• Supports all SIP status codes.
• Operates as a stateful proxy or redirect proxy. As a stateful proxy, it will proxy SIP requests on behalf of
• SIP devices. As a redirect proxy, it will redirect the SIP device to the appropriate destination.
• Supports forwarding of REGISTER messages to downstream SIP devices.
• Provides a visual display of registered SIP devices using the Web interface. All registered devices are shown on the Registrations status page along with their addresses and expirations.
• Supports SIP digest authentication as described in RFC 2617 to prevent unauthorised access to the proxy’s services.

Dial Plan and Routing Features
• Unlimited routing item entries. A routing item uses regular expressions and pattern substitution to match dialled number patterns in SIP messages and route them to the configured destination.
• Dial plan simulation. The Web interface lets a user enter a dialled address and presents the route plan after running it through the dial plan. This is useful when setting up dial plans and for diagnosing routing problems.
• Unlimited server plan entries. A server plan is a list of servers, or routes, that are attached to route item entries. A request that matches a route item entry will be forwarded to each server in the route item’s server plan until a response is received.
