Condition

In an Avaya Workplace Client deployment that includes Session Border Controller, remote users might receive the following error message: Phone service is currently limited, you can still make and receive calls.

Solution

  • On Session Border Controller, do the following:
    1. Configure the PPM mapping profile and Presence server address correctly for the SIP telephony features, presence, and PPM contacts to work.
    2. Ensure that the SIP, port number 5061, and PPM, port number 443, interfaces are configured to use the same certificate.
      ADDITIONAL INFORMATION:
      Often, the SIP interface is configured to use a third-party certificate, but the PPM interface uses the demo certificate.
  • On Communication Manager, in the Private-Numbering table, ensure that the SIP extension range is mapped to the SIP trunk of Session Manager. If it is not mapped, Avaya Workplace Client cannot subscribe to the full telephony services.
