Sample Code
The following sample code demonstrates the application implementation of the
RvSipCallLegTranscCreatedEv() callback. In this implementation, the
application specifies that it wishes to handle only INFO requests and instructs
the SIP Stack to handle all other requests. The application does not exchange
handles with the Stack.
