DHCP Server setup. To resolve this problem, you have
two options:
Option A:
1. In your DHCP server, program
Mitel proprietary Option 135
(Proxy Server) as String type
and enter a socket value in the
format of <ip:port>
For example: 192.168.1.4:3128
where 192.168.1.4 is the IP
address of the MSL server and
3128 is the http proxy port
2. Reboot the webset to get the
new DHCP option.
Option B:
1. Program the MSL server to also
be your DHCP server. For
information on how to configure
the MSL server, refer to the
Mitel Standard Linux (MSL)
Installation and Maintenance
Guide available from Mitel
Online
2. Reboot the webset to get the
new DHCP option.

Fails to register. Remains in
DHCP discovery.
The CITELlink gateway
contains two Network Layer
Processors (NLPs) referred
to as NLPA and NLPB.
Each processor supports
12 phones and the
processors require their
own unique IP addresses.
When using DHCP, the
DHCP server must have at
least two spare IP
addresses (one for each
NLP).
Enter a unique IP address in the
myIPAdress field of both the NLPA
and the NLPB forms. In addition,
we recommend that you connect
the CITELlink gateway to the
ACCESS PORT of the Layer2
switch for the associated VLAN.
Refer to the 3300 ICP CITELlink
Gateway Installation and
Configuration Guide for
instructions.
