SmartAX MA5616 Multi-service Access Module
Configuration Guide
Context
The voice over IP (VoIP) service uses the IP packet switching network for transmission after
the traditional analog voice signals are compressed and packetized, to reduce the cost of the
voice service.
For details about the VoIP service, see Voice in the Feature Description.
The function and application of the SIP interface are similar to the function and application of
the MG interface. The MA5616 can also function as a voice over IP gateway (VGW) component
in the IMS architecture. In the downstream direction, it provides the access to PSTN users; in
the upstream direction, it is connected to the IMS system through the SIP interface, providing
the VoIP service by working with the IMS core.
Prerequisite
According to the actual network, a route from the MA5616 to the IMS core network device must
be configured to ensure that the MA5616 and the IMS core network device are reachable to each
other.

7 Configuring the Voice Service
Remarks
It is used as the upstream VLAN of the
VoIP service to be configured. Note that
the media stream and the signaling
stream can use the same VLAN or
different VLANs. The result is
determined according to the negotiation
with the upstream device.
It is used as the upstream port for
configuring the SIP signaling.
These IP addresses must be selected
from the media and signaling IP address
pools. The media and signaling IP
address pools consist of all the IP
addresses of the L3 interface of the
media and signaling upstream VLAN.
