4.2 VoIP Function

The VoIP function refers to the function that the SIP server performs. The SIP server is a
software module that operates on the feature server. Based on the standard SIP protocol, it
provides the gateway function for smooth signal processing between the existing phones
and standard SIP user devices. In addition it provides the function that allows the standard
SIP user devices to interoperate with the OfficeServ 7070 phones.

4.2.1 VoIP Network

Because the MGI module embedded in the OfficeServ 7070 is used when calling other
system through VoIP networking, no separate MGI board is needed. However, for the
number of channels needed to meet user requirements, a separate license is required.

4.2.2 VoIP Trunk Interface

The OfficeServ 7070 provides a VoIP trunk interface (SIP). The OfficeServ 7070 controls
calls and establishes a communication path through the embedded MGI module.

4.2.3 Proxy Server

The OfficeServ 7070 operates as an SIP device controller to allow the standard SIP devices
(user agents) specified by the RFC3261 SIP standard to interoperate with the OfficeServ
7070's call service. It operates as a proxy server to perform the routing operations for call
processing requests received from an SIP device, such as call setup, canceling and release.
In addition, it performs the status management for SIP devices and a smooth call service
between SIP devices.

4.2.4 Registering Users

An SIP interface user is identified by an SIP address in an email address format. The user
registration function stores and manages the IP address and priority of the current user for a
specified period of time. Then it provides this user information when another user,
authenticated through the authentication procedure, requests it.

4.2.5 SIP Phone Configuration

If the user configures a standard SIP phone so that it can be used as an OfficeServ 7070
phone and enters its phone number and user ID in the call server, the SIP server creates a
configuration file for it. If the user then operates it, the configuration data required at the
initial stage is downloaded into the TFTP. This configuration file contains the OfficeServ
7070 system phone number, user name, and codec information, etc. assigned to the user's
SIP phone and is used to configure the user's SIP phone.
