XCALLY Motion can potentially be integrated with any ASR/TTS system based on MRCP.

In the following section you find an example of this kind of integration (Lumenvox).

This configuration activity is recommended for advanced users only (system engineers)

LumenVox Integration

Configuring UniMRCP to work with LumenVox

UniMRCP is a pre-requisite of this integration: if it is not installed yet, see on this page how to do it.

You need to configure:

The mrcp.conf file in /etc/asterisk/
The res-speech-unimrcp.conf file in /etc/asterisk/
The unimrcpclient.xml in /usr/local/unimrcp/conf/
The lumenvox.xml in /usr/local/unimrcp/conf/client-profiles/

Step 1: Configure res_unimrcp.so module by editing the mrcp.conf file

Here you can find a working mrcp.conf example (to be modified accordingly with your environment):

[general]

default-asr-profile = speech-lumenvox-mrcp1

default-tts-profile = speech-lumenvox-mrcp1

; UniMRCP logging level to appear in Asterisk logs. Options are:

log-level = DEBUG

max-connection-count = 100

offer-new-connection = 1

; rx-buffer-size = 1024

; tx-buffer-size = 1024

; request-timeout = 60

[speech-lumenvox-mrcp1]

; +++ MRCP settings +++

version = 1

;

; +++ RTSP +++

; === RSTP settings ===

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; Set this to the LumenVox Media Server's IP:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

server-ip = X.X.X.X

server-port = 554

; force-destination = 1

resource-location = media

speechsynth = speechsynthesizer

speechrecog = speechrecognizer

;

; +++ RTP +++

; === RTP factory ===

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; Set this to the XCALLY Motion machine's IP:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

rtp-ip = X.X.X.X

; rtp-ext-ip = auto

rtp-port-min = 4000

rtp-port-max = 5000

; === RTP settings ===

; --- Jitter buffer settings ---res-speech-unimrcp.conf

playout-delay = 50

; min-playout-delay = 20

max-playout-delay = 200

; --- RTP settings ---

ptime = 20

codecs = PCMU PCMA L16/96/8000 telephone-event/101/8000

; --- RTCP settings ---

rtcp = 1

rtcp-bye = 2

rtcp-tx-interval = 5000

rtcp-rx-resolution = 1000

1) Set the server-ip directive pointing to the Lumenvox Media Server IP.

2) Set the server-port directive to the Lumenvox Media Server port.

3) Set the rtp-ip directive pointing to the XCALLY Motion IP.

Step2: Configure res_speech_unimrcp.so modules by editing the res-speech-unimrcp.conf file

Here you can find a working res-speech-unimrcp.conf example:

[general]

; UniMRCP named profile. Options are:

;unimrcp-profile = uni2 ; UniMRCP MRCPv2 Server

;unimrcp-profile = uni1 ; UniMRCP MRCPv1 Server

;unimrcp-profile = lv2 ; LumenVox MRCPv2 Server

unimrcp-profile = lv1 ; LumenVox MRCPv1 Server

;unimrcp-profile = nss2 ; Nuance MRCPv2 Server

;unimrcp-profile = nss1 ; Nuance MRCPv1 Server

; UniMRCP logging level. Options are:

log-level = DEBUG

; Preloaded grammars

[grammars]

;grammar-name = path-to-grammar-file

; MRCPv2 properties (recognizer and generic header fields)

; http://tools.ietf.org/html/draft-ietf-speechsc-mrcpv2-20#section-9.4

[mrcpv2-properties]

Recognition-Timeout = 20000

No-Input-Timeout = 15000

; MRCPv1 properties (recognizer and generic header fields)

; http://tools.ietf.org/html/rfc4463#section-8.4

[mrcpv1-properties]

Recognition-Timeout = 20000

No-Input-Timeout = 15000

1)Set the unimrcp-profile directive to lv1 (LumenVox MRCPv1 Server).

Step 3: Configure the MRCP client profile by editing the lumenvox.xml file

Here you can find a working lumenvox.xml example (to be modified accordingly with your environment):

<?xml version="1.0" encoding="UTF-8"?>

<unimrcpclient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</sip-settings>

<rtsp-settings id="LumenVox-RTSP-Settings">

<!--

</mrcpv1-profile>

</profiles>

</unimrcpclient>

1) Set the <server-ip>X.X.X.X</server-ip> sections pointing to the Lumenvox Media Server IP.

2) Set the <server-port>554</server-port> to the Lumenvox Media Server port.

Step 4: Configure unimrcpclient by editing the unimrcpclient.xml file
