Note: We highly recommend consulting an IT or network professional when configuring advanced network settings. If able, the network administrator should always check the IP address, and assign and log any static IP to avoid conflicts in the future.
Switching a phone from DHCP to a static IP can be a useful way to address connectivity issues like URL call is disabled errors. It may also alleviate some (but not all) call quality issues.
Before You Begin
- Find out your phone's password. Polycom phones in an unprovisioned, factory default state and NOT running UC4.0+ firmware should be able to utilize 456 or 123. Otherwise, use the MAC password.
- Next, determine the phone's current IP address and a static IP address (along with subnet and gateway) to assign to the phone.
