Voice Gateway Configuration
As with media servers and application 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 ISN infrastructure, even
if the same server(s) handle both ASR and TTS functions. The default English ASR and TTS server
names are:
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 ISN infrastructure, even
if the same server(s) handle both ASR and TTS functions. The default English ASR and TTS server
names are:
For ASR:
asr-en-us
and
asr-en-us-backup
For TTS:
tts-en-us
and
tts-en-us-backup
These host names should be set to resolve to the VIP address of the content rule that governs each
service. (Note that in the CSS sample above, both ASR and TTS functions are handled by the same
content rule and group of resources.)
service. (Note that in the CSS sample above, both ASR and TTS functions are handled by the same
content rule and group of resources.)
The voice gateway config would contain ip hosts that look like this:
ip host asr-en-us 10.1.1.12
ip host asr-en-us-backup 10.1.1.12
ip host tts-en-us 10.1.1.12
ip host tts-en-us-backup 10.1.1.12
If a network design contains separate MRCP servers for ASR and TTS functions, CSS would contain
separate services, separate source groups (if needed), and two separate content rules / vip
addresses—one for ASR and another for TTS resources.
separate services, separate source groups (if needed), and two separate content rules / vip
addresses—one for ASR and another for TTS resources.
In this case, the CSS content rules might look like this:
content ASR
add service asr1
add service asr2
primarySorryServer asr3
protocol tcp
port 554
vip address 10.1.3.12
add service asr2
primarySorryServer asr3

vip address 10.1.3.12
