Troubleshooting

You can use any existing Bfv problem solving tools to troubleshoot your T.38 application. Use the log files created by these tools to understand what is happening and modify your application. See Chapter , Debugging on page 91 for more information about these tools.

Dialogic has provided a debug_control mode for T.38 problem solving (use under guidance of Dialogic Technical Services and Support). See Volume 1 of the Bfv API Reference Manual for more information.
