TTS and ASR Services Intermittently Fail

Publication Date:  2015-06-29 Views:  196 Downloads:  0
Issue Description
When the U2990 is used, the Text To Speech (TTS) and Automatic Speech Recognition (ASR) services become unavailable intermittently.
Handling Process
1. Query information about all sites.
LST RCWSCFG:;
If the following information is displayed, the TTS and ASR functions are not configured for site 1:
------------------
WS number  Management module number  WS type     Module number  TTS capability   ASR capability   RES capability  

0          184                       MSU audio   472            NULL             NULL             IVR, CONF, FAX, TTS, ASR
1          184                       MSU audio   473            NULL             NULL             IVR, CONF, FAX,
2. Delete all resources of site 1.
RMV RCWSCFG: WSNO=1;
3. Add resources for site 1 and configure the TTS and ASR functions.
ADD RCWSCFG: WSNO=1, WSTYPE2=MSUA, MODULENO=473, RESCAP=IVR-1&CONF-1&FAX-1&TTS-1&ASR-1;
4. Restart the MSU board.
5. If the fault still persists, obtain help through the channels described in Help Channels.
Root Cause
A unique site is configured on one MSU board to provide services such as IVR, fax, TTS, and ASR. The services available on each site can be configured as preferred. The MSU boards work in load balancing mode so service requests may be distributed to all sites on the MSU boards. When a service request is distributed to a site that has no TTS and ASR functions configured, the TTS and ASR services certainly are unavailable.
