Polycom DHCP Record Notes

Time server settings

Options 002, 004, and 042 configure the time server on the DHCP server. Alternatively, you can choose to configure the time server in Interaction Administrator. For more information, see Configure the Time Server.

• Option 002: The values for Option 002 require hexadecimal numbers. To convert values to hexadecimal numbers, see How to Calculate the Hexadecimal Value for DHCP Option 2 (time offset).

• Options 004 or 042: Set either option 004 or 042, not both. Genesys recommends setting multiple values in the Option 004 or 042 record, particularly for CIC systems using TLS, to provide redundancy. If you do not specify values for one of these options, the provisioning server uses the default location and SNTP server settings provided in the phone configuration files, based on the region of the phone.

Option 015

Use the DNS domain for the voice VLAN for the Option 015 record.

Option 160

• Option 160 is the primary default record that Polycom phones use to find the provisioning server.

• Option 160 takes precedence over Option 066 (the secondary default record that Polycom phones use to find the provisioning server). Genesys recommends that you do not use Option 066 for Polycom phones.

• Switchover environments: Ensure that you created the DNS Host (A) records as described in Create DNS Host (A) Records for Switchover and DNS Service Location (SRV) records as described in Create DNS Service Location (SRV) Records for Switchover. For DHCP Option 160, use the DNS Host (A) provisioning record in the URL.
