IP Networking
S 1 INTRODUCTION
ECTION
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.
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.
S 2 IP TRUNKS
ECTION
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 on page 7-1
instructions.
To set up IP trunks:
1. Connect the system to the Data Network. (Refer to
detailed instructions.)
2. Configure the IP trunks.
3. Configure the SIP information.
4. Configure the F-Route.
2.1 Configure IP Trunks
When installing a VoIP daughter board in the NEC SL2100 system, external line ports are allotted in
accordance with the number of Licensed ports for the particular IP Application.
The NEC SL2100 system now has the required information about the remote destinations and the SIP
configuration is complete. The only remaining task is to configure F-Route to route calls to remote
destinations via the IP trunks. F-Route configuration is discussed in detail in the Automatic Route
Selection (ARS) feature in the NEC SL2100 Programming Manual.
