Cisco Unified CCX VoiceXML Application Troubleshooting Tips

The following are helpful tips when troubleshooting your voiceXML application:

• Check the Cisco Unified CCX subsystems in service: CMT, JTAPI, MRCP ASR&TTS, Voice Browser.

• Test the URI in the Web browser.

• Check the Provider selection.

• Validate files: VXML, grammar, audio.

• Check file fetching locations.

• Use a DTD to check for the correct syntax.

• Do performance tuning: exclude the DTD and use caching facilities (VXML, HTTP)

• In the Cisco Unified CCX system, trace the contact flow:

  • The SS_VB subsystem is used to control tracing for the Voicebrowser, and the “Debugging” level provides debug output.

  • Other related subsystems to check:

    • SS_MRCP_TTS

    • SS_MRCP_ASR

    • SS_CMT

• Check the log file
