1.2 Gateway Description
The MP-40x (MediaPack) is an Integrated Services Digital Network (ISDN), Basic-Rate
Interface (BRI) VoIP media gateway. The MediaPack is best suited for small to medium
size enterprises, branch offices, or residential media gateway solutions implementing
ISDN. The MediaPack seamlessly migrates these environments to VoIP by connecting
legacy ISDN telephones, fax machines, and PBX systems (as well as for integration with
new IP-based PBX architecture) with BRI lines to the IP network. The MediaPack gateways
enable users to make free local or international telephone or fax calls between distributed
company offices, using their existing telephones or faxes. These calls are routed over the
existing network ensuring that voice traffic uses minimum bandwidth.
This stand-alone MediaPack BRI VoIP gateway offers superior voice technology as well as
state-of-the-art end-users features such as T.38 fax relay and G.168-2002 compliant Echo
Cancellation. In addition, low bit-rate (LBR) voice coders are supported, saving valuable
bandwidth.
The MediaPack complies with leading VoIP standards and is designed and tested to be
fully interoperable with leading softswitches and SIP servers. The MediaPack supports
Session Initiation Protocol (SIP) and H.323 protocols, enabling the deployment of VoIP
solutions in environments where each enterprise or residential location is provided with a
simple media gateway.
The MediaPack gateway spans a range of up to four BRI S/T interface ports (RJ-45) for
connection to an enterprise PBX (FXO), ISDN phones, fax machines, and computers. The
ports can be configured for network (NT) or terminal equipment (TE) side for interfacing
with ISDN (CO) or PBX.
Each BRI S/T port supports up to two voice/data channels (i.e., two B-channels) and one
signaling channel (i.e. D-channel). Thus, the MediaPack supports up to eight simultaneous
VoIP channels. In addition, the gateway can support up to 32 TE devices (e.g., ISDN
telephones) when implementing an S/T bus (8 devices per BRI S/T port).
In addition to the four BRI channels, the MediaPack provides a fifth BRI interface for
supporting lifeline telephony services in the event of a power outage. This lifeline BRI
interface supports an ISDN connection to the ISDN/PSTN network (instead of the IP
network), and can connect at least one ISDN phone to the ISDN network.
The MediaPack supports ISDN fallback in case of power failure or network deterioration. In
such a scenario, the ISDN port is switched to the redundant port, which is connected to the
ISDN network (i.e., PSTN).
The MediaPack provides two 10/100 Base-TX Ethernet ports for interfacing with the Local
Area Network (LAN) and Wide Area Network (WAN). In addition, the MediaPack provides
integrated router capabilities such as NAT, DHCP Server and Client and a PPPoE client for
the Ethernet interfaces.
The MediaPack gateway is a compact device that can be mounted on desktop, wall, or in a
standard 19-inch rack using shelf racks.
The MediaPack gateway offers remote management and configuration by providing an
Embedded Web Server. This user-friendly Web interface can be accessed by using
standard Web browsers (Microsoft™ Internet Explorer or Firefox).

1.3 SIP Overview
SIP (Session Initialization Protocol) is an application-layer control (signaling) protocol used
on the MediaPack 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 Description Protocol (SDP)
messages 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, on the MediaPack, complies with the IETF (Internet
Engineering Task Force) RFC 3261 (refer to http://www.ietf.org).

1.4.3 Telephony Capabilities
1.4.3.1 Supplementary Services
The MediaPack SIP gateway supports the following supplementary services:
Hold / Retrieve; refer to 'Call Hold and Retrieve' below.
Transfer (Refer and Replaces); refer to 'Call Transfer' on page 20.
Call Forward (3xx Redirect Responses); refer to 'Call Forward' on page 21.
Call Waiting (182 Queued Response); refer to 'Call Waiting' on page 21.
The above services are permanently active and cannot be disabled.
For example setups of Supplementary Services, refer to Section 'Configuring
Supplementary Services' on page 168'.
1.4.3.1.1 Call Hold and Retrieve
Call Hold and Retrieve can be initiated by using the corresponding features of the ISDN
Phone.
Hold is performed by sending a REINVITE with the IP address 0.0.0.0 and ‘a=inactive’ in
the SDP.
The ISDN user can retrieve the call using the appropriate features of the ISDN phone.
1.4.3.1.2 Call Transfer
The system supports call transfer by the SIP side. The system supports the following two
types of call transfers:
Consultation Transfer (Refer and Replaces)
The common way to perform a consultation transfer is as follows:
In the transfer scenario, there are three parties: Party A = transferring, Party B =
transferred and Party C = transferred to.
•A Calls B.
•B answers.
•A holds the call and dials a call to C.
•A connects B to C, and then A disconnects.
•After the transfer is complete, the B and C parties engage in a call.
Blind Transfer (Refer)
Blind transfer is performed after we have a call between A and B, and party A decides
to transfer the call to C immediately without speaking with C. It can do so by sending a
REFER message.
The result of the transfer is a call between B and C (similar to consultation transfer,
but skipping the consultation stage).
