2. Verify or set SSON to 242 which is the default value.
3. Administer the DHCP server option 242 to include MCIPADD=xxx.xxx.xxx.xxx where
xxx.xxx.xxx.xxx is the call server IP address.
4. Verify that the DHCP server and the deskphone are on the same VLAN.
5. Verify the DHCP server port 67 and or the DHCP client port 68 are not blocked on the
switch.
6. Verify the configuration of the DHCP Relay Agent on the switch or on a separate PC, for
example, MS Windows Server 2000/2003 whether the deskphones and DHCP Server are
placed on different networks or subnets. DHCP broadcast messages do not, by default,
cross the router interface.
Note:
Do not embed spaces in DHCP Option 242 strings. For more information, see DHCP

Proposed solution for script-configured deskphones
Procedure
1. Edit the 46xxsettings.txt file to contain a valid Call Server IP address with the line SET
MCIPADD xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the Call Server IP address.
2. Verify that the 96xxupgrade.txt file contains the line GET 46xxsettings.txt as the last
command line of the upgrade file.
3. Verify that the deskphone can reach the HTTP server and whether the HTTP server is
activated.
4. Verify that the 96xxupgrade.txt and 46xxsettings.txt files are placed in the proper directory
of the HTTP server to access these files.
Proposed solution for LLDP-configured deskphones
About this task
For LLDP-configured deskphones, activate the switch the deskphone is connected to for LLDP.
This is currently only possible with Extreme switches. Activating the switch for LLDP enables the
switch to send appropriate IP addresses using Avaya/Extreme Proprietary HTTP and/or HTTPS
Server and/or Call Server TLVs.
Note:
The deskphone obtains the HTTP and or HTTPS Server and Call Server IP addresses from LLDP
only if the addresses were not configured through other means such as DHCP Server, Script File,
or statically.
Note:
Set the switch LLDP repeat timer to less than 30 seconds.
