Adjusting Local SIP Ports

Adjusting local SIP ports is commonly done when disabling Strict Register on a Fortigate router to resolve NAT configuration issues. Adjusting local SIP ports can also be completed as a last resort if a device is causing duplicate ports or port shuffling. If the local SIP ports are being adjusted, it needs to be completed for all phones on the same network.

To adjust the Local SIP Port on a Polycom

  1. In a browser on a computer on the same network as the phone, navigate to phone’s local IP address. You will need to use this format: https://xxx.xxx.xxx.xxx.
  2. Log in as Admin and enter the phone's MAC password.
  3. Click Settings.
  4. Click SIP.
  5. Enter a Local SIP Port. Typically we use ports 16000, 16001, 16002, etc. Note: Do not assign ports below port 1024, as the lower ports are typically used by other applications. Additionally If you are assigning a local SIP Port to more than one phone, each phone will need a unique port.
     
  6.  After setting the port assignment, click Save.
  7. If the phone does not take the configuration at first, reboot the device and try to assign the port again.
