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.
Connection test with Common Carrier is required.
