User's Manual 1. Overview
1 Overview
The MediaPack series analog Voice-over-IP (VoIP) Session Initiation Protocol (SIP) media
gateways (hereafter referred to as device) are cost-effective, cutting edge technology
products. These stand-alone analog VoIP devices provide superior voice technology for
connecting legacy telephones, fax machines and Private Branch Exchange (PBX) systems
to IP-based telephony networks, as well as for integration with new IP-based PBX
architectures. These devices are designed and tested to be fully interoperable with leading
softswitches and SIP servers.
The device is best suited for small and medium-sized enterprises (SME), branch offices, or
residential media gateway solutions. The device enables users to make local or
international telephone and / or fax calls over the Internet between distributed company
offices, using their existing telephones and fax. These calls are routed over the existing
network ensuring that voice traffic uses minimum bandwidth. The device also provides SIP
trunking capabilities for Enterprises operating with multiple Internet Telephony Service
Providers (ITSP) for VoIP services.
The device supports the SIP protocol, enabling the deployment of VoIP solutions in
environments where each enterprise or residential location is provided with a simple media
gateway. This provides the enterprise with a telephone connection (i.e., RJ-11 connector)
and the capability to transmit voice and telephony signals over a packet network.
The device provides FXO and/or FXS analog ports for direct connection to an enterprise's
PBX (FXO), and / or to phones, fax machines, and modems (FXS). Depending on model,
the device can support up to 24 simultaneous VoIP calls. The device is also equipped with
a 10/100Base-TX Ethernet port for connection to the IP network. The device provides
LEDs for indicating operating status of the various interfaces.
The device is a compact unit that can be easily mounted on a desktop, wall, or in a 19-inch
rack.
The device provides a variety of management and provisioning tools, including an HTTP-
based embedded Web server, Telnet, Element Management System (EMS), and Simple
Network Management Protocol (SNMP). The user-friendly, Web interface provides remote
configuration using any standard Web browser (such as Microsoft™ Internet Explorer™).
The figure below illustrates a typical MediaPack VoIP application.

1.1 MediaPack Models
The analog MediaPack 1xx models and their corresponding supported configurations are
listed in the table below:
Table 1-1: MediaPack 1xx Models and Configurations
MediaPack Model FXS FXO Combined FXS /
FXO Number of Channels
MP-124 Yes No No 24
MP-118 Yes Yes 4 + 4 8
MP-114 Yes Yes 2 + 2 4
MP-112* Yes No No 2
* The MP-112 differs from the MP-114 and MP-118 in that its configuration excludes the
RS-232 connector, Lifeline option, and outdoor protection.
1.2 SIP Overview
Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol used on
the gateway for creating, modifying, and terminating sessions with one or more
participants. These sessions can include Internet telephone calls, media announcements,
and conferences.
SIP invitations are used to create sessions and carry session descriptions that enable
participants to agree on a set of compatible media types. SIP uses elements called Proxy
servers to help route requests to the user's current location, authenticate and authorize
users for services, implement provider call-routing policies and provide features to users.
SIP also provides a registration function that enables users to upload their current locations
for use by Proxy servers. SIP implemented in the gateway, complies with the Internet
Engineering Task Force (IETF) RFC 3261 (refer to http://www.ietf.org).
The SIP call flow, shown in the figure below, describes SIP messages exchanged between
two devices during a basic call. In this call flow example, device 10.8.201.158 with phone
number 6000, dials device 10.8.201.161 with phone number 2000.
