CSS Configuration for ASR/TTS Servers: Keepalive Method

For the MRCP ASR/TTS servers, a socket-level keepalive is used. By implementing a socket
keepalive, the CSS will make a connection to the MRCP port to validate that the MRCP server
is running. The service is considered down if unable to connect to port 554 for MRCP traffic.

To configure the CSS MRCP Keepalive, use the following:

keepalive type tcp

keepalive port 554

Note: For detailed instructions on implementing keepalives for CSS, refer to 

 (http://www.cisco.com/en/US/products/hw/contnetw/ps792/

CSS Configuration for ASR/TTS Servers: Keepalive Times

Because these services are directly involved in processing voice calls, the shortest possible
failover detection is desired. As such, set the following keepalive parameters:

keepalive retryperiod 2

keepalive maxfailure 1

CSS Configuration for ASR/TTS Servers: Groups

Define a group for the participating ASR/TTS Servers if your configuration requires source
groups (see the discussion of Groups in the "

CSS Configuration for ASR/TTS Servers: Activate Services, Group, and Rules

CSS Configuration for ASR/TTS Servers: Voice Gateway

As with media servers and Call Servers, the ASR / TTS names should resolve to the VIP address
running the content rule for ASR and/or TTS on the CSS. This name resolution occurs at each
voice gateway. Note that ASR and TTS requests each utilize separate names within the Unified
CVP infrastructure, even if the same server(s) handle both ASR and TTS functions. The default
English ASR and TTS server names are:
