SECTION 1 INTRODUCTION
1
IP Networking uses VoIP technology to connect two or more telephone
systems together. This allows calls to be made between sites without
using the public telephone network. This saves considerable money, and
makes communication between sites much easier.
SECTION 2 IP TRUNKS
The SIP Trunks method of networking allows connection to SIP devices.
This could be a PBX system or a third-party product. When using SIP, the
feature set is limited and the advanced networking features cannot be
used.
Refer to SIP Trunking for a a detailed description of SIP trunking and for
set up instructions.
To set up IP trunks:
1. Connect the system to the Data Network. (Refer to General IP
Configuration for detailed instructions.)
2. Configure the IP trunks.
3. Configure the SIP information.
4. Configure the F-Route.
1. The voice quality of VoIP is dependent on variables such as available bandwidth, network latency and Quality of
Service (QoS) initiatives, all of which are controlled by the network and Internet Service Providers. Because
these variables are not in NEC control, it cannot guarantee the performance of the user’s IP-based remote voice
solution. Therefore, NEC recommends connecting VoIP equipment through a local area network using a Private
IP address.
