I have developed a custom application based on the Cisco GSAPI as a .NET based console application. This application needs to intercept communicate with Cisco ISR-G2 Router and verify the calling number from external database in order to determine the next action i.e., whether to Allow/ Redirect/ Deny the call.
I am successfully able to register our application with the XCC provider on router and the router sends me back proper “ResponseXccRegister” message.
However, when app responds to the SolicitXccProbing with ResponseXccProbing message, it sends back an XML PARSER error message. The message format is similar to what Cisco suggests in the GSAPI document. We are not very sure what's wrong here!
Below are logs,
