Media Gateway SIP
1. General Description
Media Gateway-Session Initiation Protocol 16-channel type (MG-SIP16) is an interface that enables your
system to build a multi-service and reliable Voice over IP (VoIP) network using Session Initiation
Protocol (SIP) defined by IETF. SIP is an application-layer control protocol that can initiate call setup,
routing, authentication, and transfer feature messages to endpoints.
Up to 16 channels of extensions in an IPX network can communicate with the outside SIP network via an
MG-SIP16 at the same time. As MG-SIP16 complies with small and middle sized remote offices flexibly,
more offices can profit from Peer-to-Peer VoIP services using IP telephony.
The MG-SIP16 supports the SIP standard terminals based on RFC3261. Thereby, the MG-SIP16, which
is controlled by MGC (PHI) of the IPX, provides a full array of call routing capabilities to maximize
network performance in the packet voice network (SIP network). The MG-SIP16 provides the system
with a flexible and cost-efficient network environment without wasting the accumulated assets of the
NEC products.
Note: Connection test with Common Carrier is required.

2. Operating Procedure
None.
3. Service Conditions
1. PHI is essential to perform this feature. This is included in MGC and it controls the MG-SIP16 via
TCP/IP.
2. MG-SIP16 supports 1 to 16 channels.
3. The maximum number of MG-SIP16s accommodated per system (including MC-MG with PFT) and
available channels are as follows, however, note that a maximum of simultaneous speech channels
available per LP, including other ISDN channels, is 460 channels.
Note 1: The maximum number of devices and channels per system is calculated on the
condition that each device accommodated is set to the full capacity of channels. The
number of devices varies depending on the total accommodated channels.
Note 2: When 6144 channels are occupied only by MG-SIP16, other devices cannot be
connected.
4. The number of Internal PHIs is one per system, except for UMG. For UMG, see Service Condition 22.
5. Speech channel is established by Virtual Trunk. Regardless of the registration number, the Virtual
Trunk occupies channels on a 1HW (4-Group) basis. For example, ff a single channel is registered,
the whole HW (32-channel) is occupied exclusively for the one single channel; other-type Virtual
Channel cannot be registered.
6. Virtual Trunk is registered to Virtual PIM.
7. MG-SIP16 makes a connection using SIP Server, which helps to create multi-location connection. SIP
server can use Proxy Server and Registry Server. User Agent (UA) has been registered to SIP Server.
8. Voice, FAX, DTMF (PB Signaling) communication can be established by connections via MG-SIP16.
9. IP Masquerade feature can make a VoIP connection between Private IP Address and Global IP Address.
IP Masquerade feature is to translate UDP and TCP Ports, thereby; it can connect multiple Private IP

MG-SIP Page 8 of 75 5/8/2009
Addresses to single Global IP Address. There is no special equipment for performing IP Masquerade.
However, delay and bandwidth increase might be caused on the connection.
10. Feature Services available in the SIP network are described in Appendix A.
11. When 3rd-party SIP-based terminals (such as SIP Gateway, SIP Terminal, SIP Server) are used in the
SIP network, test these terminals in advance if they are available to use. Note that the terminal cannot
be managed as a station under IPX.
12. Additional services (such as REFER) on the SIP procedure are not provided in this system. See SIP
Message Support section for additional information.
13. Tone and holding tone to SIP network is generated by MG-SIP16. When MGC (PHI) external holding
tone is selected by ASYDL command, the information is provided via MGC.
14. When making a route for MG-SIP16, register the route for each MG-SIP16. A route cannot be shared
by multiple MG-SIP16s.
15. Before using MG-SIP16, it is required to register IP licenses by the AMGIL command. If the number
of IP licenses is not enough to use the SIP terminals, all the terminals cannot register to the system.
16. MG Registration Status can be displayed by using the DIMG command.
17. MGC transfers only Voice RTP Payload. Therefore, Jitter-Buffer Control, Echo Canceller, PAD
Control do not affect the connection. The connection is controlled by end points.
18. PB Receiver becomes invalid while receiving an announcement for AUTOMATED ATTENDANT
[A-82]/REMOTE ACCESS TO SYSTEM [R-2] when Incoming Call terminates to MG-SIP16.
19. MG-SIP16 does not support ring down service.
20. To use VLAN feature of MG-SIP16, connect Switch supporting VLAN feature. MG-SIP itself does
not support VLAN.
21. To use FAX communication feature of MG-SIP16, specify the FAX settings by ARTI/ARTIN
command.
The FAX communication has constraints as follows:
• FAX communication can be established only when G711 is assigned to payload for Voice and FAX.
• FAX communication can be established only when Payload Sizes for Voice and FAX are the same.
• To establish FAX communication with SIP network via MG-SIP16, be sure to assign G711 as
Payload
Type for all the FAX accommodated in the system.
22. The following provides the port number to be used in this system. If the firewall is applied to in your
network, unblock the following ports.

23. Alternate routing to PSTN line can be activated in the case of the following connection failure on IP
network.
• Ether cable failure on MG-SIP16’s LAN side (IPX network) connector.
• Network failure between IPX and MG-SIP16.
• MG-SIP16 failure (such as power-off, etc.) ÆAlternate routing is activated after health check
timeout detection.
• Ether cable failure on MG-SIP16’s WAN side (SIP network) connector ÆAlternate routing is
activated after health check timeout detection.
• Network failure between MG-SIP16 and carrier’s SIP server ÆAlternate routing is activated after
originating connection timeout (6 seconds).
• MG-SIP16 receives error response from carrier’s SIP server ÆAlternate routing is activated after
receiving error response (400, 408, 500, and 503).
• All the available channels are busy or in make-busy state.
