Deployment Guide for the Polycom CX700 IP Phone

Step 1.1 - Configure DHCP

The first step is to make sure the Polycom CX700 phone can get an IP address and the necessary DNS (and potentially WINS) information it needs to locate a time service, certificate chain and pool running the Device Update service. The figure below shows both WINS and DHCP Option 119 configured but typically you will only configure Option 119 and leave the WINS scope options out.

Polycom CX700 phones look for a WINS entry matching the NetBIOS name of <DHCPDomain> (for example, CONTOSO or CONTOSO.COM if you sign in using the domain FQDN in the Domain\User name: field). All examples in this document were done using the domain FQDN (so WINS was not used).

If the <SIPDomain> value that users sign in to their Polycom CX700 phones with is different than the domain where their domain controller is located, you can configure DHCP Option 119 to include a list of all the domains to check for a DC. For instructions on configuring Option 119, refer to How to Configure DHCP Option 119 on page 3-43.

Step 1.2 - Configure DNS

The following DNS records are required for upgrading but some are only required for a specific phase (for example, ucupdates-r2 is only used from 1.0522.101 to 3.5.6907.35):
