Provider becomes IN_SERVICE immediately
Symptom   
When creating as ASR/TTS provider, its status becomes IN_SERVICE immediately. This 
happens even before creating any servers for it.
Error Message   The ASR/TTS provider status incorrectly shows 
IN_SERVICE
.
Possible Cause   
After deleting a provider and all the servers along with it, if a new provider is created, it 
continues to use the previous configuration and does not get refreshed.
Recommended Action   
Click Refresh or Refresh All for that provider. This will cause the status of the 
provider to go OUT_OF_SERVICE as expected.
TTS Prompt does not play
Symptom   
Callers do not hear a TTS prompt when a TTS prompt is expected.
Error Message   
None
.
Possible Cause   
The cause of the problem might be one of the following:
  •
The language specified in the Override Language field in the TTS Prompt step is not available.
  •
The text referenced in the Text Input expression is larger than 20 KB.
  •
There are not enough MRCP TTS licenses for the MRCP TTS Provider that is being used. Licensing 
can be implemented in different ways by different MRCP TTS vendors. It may happen that 
depending on the licensing scheme of the vendor there may not be enough MRCP TTS licenses 
configured for the language being used.
  •
When using multiple TTS providers, each with a different set of supported languages, the 
appropriate TTS provider (the one that supports the desired language) might not get used. This might 
be because the provider is not selected as the Default TTS provider and therefore some other 
provider might get used.
Recommended Action   
Depending upon the cause, do one of the following:
  •
If the language specified is not available, from the Cisco Unified CCX Administration web page, 
choose Subsystems > MRCP TTS and check whether the MRCP TTS server for the Override 
Language is configured. If it is not, configure a new MRCP TTS server with the desired language 
and then reload the corresponding MRCP Provider.
  •
Text larger than 20 KB is not allowed. Make sure that you are using less than 20 KB of text.
