•RTP uses a base port of 10,000

The MRCP configuration file

Installing the MRCP feature on Avaya IR creates a configuration file (/vs/sproxy/cfg/mrcp.cfg) and the default settings shown in the following table.

The configuration file sets parameters for the ports used for signaling and the timing intervals that Avaya IR uses to determine if it has lost touch with speech resource servers. Under most circumstances, there is no need to change these default settings.

Parameter

Description

Default Setting

RTPNumberofPorts

The number of ports on Avaya IR available for RTP

1000

 

connections to MRCP servers.

 

 

Note:

 

 

The default setting is higher than the number of

 

 

ports that Avaya IR can support for ARS and TTS

 

 

combined. This helps prevent port conflict.

 

RTPBasePort

The base port number on Avaya IR for the range of

10000

 

ports used for RTP connections to MRCP servers.

 

 

This value, combined with the RTPNumberofPorts

 

 

value, defines the range of ports reserved for

 

 

connections to MRCP servers.

 

 

ASR requests use the lower half of the range, while

 

 

TTS requests use the upper half of the range.

 

 

The default setting has been set to prevent

 

 

conflicts with the RTP ports needed for Voice Over

 

 

IP.

 

 

Change this value only if you experience port

 

 

conflicts.

 

RTPPacketRate

The rate, measured in milliseconds, at which data

20

 

is transmitted over each RTP connection.

 

 

Change this value to match the packet rate of the

 

 

MRCP server at the other end of the connection.
