Issue 6.0 NEC SL1100
9 - 20 IP Multiline Station (SIP)
13.2 IP Addressing
When a VoIPDB daughter board is installed in an SL1100 two IP addresses, in
the same network, will be required. One IP Address will be for the VoIPDB
and this address is assigned in Program 10-12-09. This IP Address is used
for IP Phones/Trunks to register and pass signaling messages. The other IP
Address is for the DSP’s and this address is assigned in Program 84-26-01.
This IP Address is used to pass voice traffic.
By default when an SL1100 with a VoIPDB is installed in a customer’s
network, the SL1100 will try and request IP Addressing information from the
local DHCP server (DHCP Client Feature). The DHCP server can provide the
SL1100 with the following information:

IP Address for VoIPDB (PRG 10-12-09)

Subnet Mask for VoIPDB (PRG 10-12-10)

Default Gateway for VoIPDB (PRG 10-12-03)
The DHCP server will NOT provide the IP address for the DSP’s (PRG 84-26-
01). This IP Address will have to be manually configured.
The DHCP Client Feature can be disabled in Program 10-63-01. When this
program is changed a reset of the SL1100 is required.
When the VoIPDB is installed, in the SL1100, the CPU NIC card is no longer
available. All connections that previously were terminated to the CPU will now
terminate to the VoIPDB. It is recommended when adding the VoIPDB to
change the IP Address of the CPU NIC card (PRG 10-12-01) to be 0.0.0.0.
13.3 IP Phone Registration Modes
The SIP MLT supports three different registration modes.
