Troubleshooting Diameter Configurations
SIP Servlets deployed on WebLogic SIP Server use the available Diameter applications to initiate
requests for user profile data, accounting, and credit control, or to subscribe to and receive
notification of profile data changes. If a SIP Servlet performing these requests generates an error
similar to:
Failed to dispatch Sip message to servlet ServletName
java.lang.IllegalArgumentException: No registered provider for protocol:
Protocol
The message may indicate that you have not properly configured the associated Diameter
application for the protocol. See “Configuring Diameter Applications” on page 4-12 for more
information.
If you experience problems connecting to a Diameter peer node, verify that you have configured
the correct protocol for communicating with the peer in “Configuring Peer Nodes” on page 4-20.
Keep in mind that WebLogic SIP Server tries only the protocol you specify for the peer
configuration (or TCP if you do not specify a protocol).
