A. This issue can occur when the voice codec for a given device, as defined by its region, is not in the list of codecs supported by the server that streams the MoH stream. For example, if a particular device is set to only use the G.729 codec, but the MoH service is only configured to stream G.711 μ-law, then this particular problem can occur. Enable G.729 in the IP Voice Media Stream App and restart the IP Voice Media Stream App service to resolve this issue. Complete these steps: • Select Service > Service Parameters and choose Cisco IP Voice Media Streaming App from the Service pull-down menu. • Under Clusterwide Parameters, select G.729 codec for Supported MoH Codecs. • Click Update. • Select IP Voice Media Stream App under Application > Cisco CallManager Serviceability > Tools > Control Center and click Restart to restart the IP Voice Media Stream App Service.
