Cause
SIP endpoints invoke the Personal Profile Manager (PPM) web service on Session Manager to discover capabilities. PPM getHomeCapabilities is used to discover the home Presence Services cluster of an endpoint. If unsuccessful, Presence and IM are not supported on the endpoint.
Solution
- Open an SSH session to Session Manager management IP address.
- Start the traceSM tool.
- When starting the capture, ensure that PPM is selected.
- Log in to the SIP endpoint.
- Verify that the endpoint sends PPM getHomeCapabilities to Session Manager.
- If Session Manager returns Fault : DataNotAvailable:
- On the System Manager web console, navigate to .
- Edit the Session Manager SIP Entity.
- Add a Listen Port.
- In the Listen Port field, enter 5061.
- In the Protocol field, enter TLS.
- In the Default Domain field, enter the login domain of endpoint devices.
- Select the Endpoints check box.
- Click Commit.
