Intel 05-2352-005 manual Compatibility Notes, Echo Cancellation With Continuous Speech Processing

Page 21

Global Call applications that use the host-based H.323 protocol stack may generate the following error message in the gc_h3r.log file if the application enables the stack to send the PROCEEDING message automatically.

!22:22:19.393 ! M_SIGNAL ! L_ERROR ! 1 ! << SIGNAL::sendProcceding: RV cmCallSendCallProceeding Failed : [-996]

This error message can be ignored. The PROCEEDING message is actually sent.

2.3Compatibility Notes

Echo Cancellation With Continuous Speech Processing

For HMP Continuous Speech Processing (CSP), the Echo Cancellation parameter default value is set to OFF (echo cancellation disabled). To conserve CPU usage/MIPs, the application should keep this parameter value set to OFF.

For additional information about CSP, refer to the Continuous Speech Processing API for Linux and Windows Library Reference and the Continuous Speech Processing API for Linux and Windows Programming Guide.

Echo Cancellation With Conferencing

For HMP conferencing, the Echo Cancellation parameter default value is set to OFF (echo cancellation disabled) for compatibility with DCB applications. This parameter must not be turned ON by the application. Enabling echo cancellation causes poor conference audio quality.

For additional information about Conferencing, refer to the Audio Conferencing API for Linux and Windows Operating Systems Library Reference and the Audio Conferencing API for Linux and Windows Operating Systems Programming Guide.

Configuring UDP/RTP Port Range

The HMP system currently defaults to UDP/RTP ports 6000 through 6100 and UDP ports 49152 through 49xxx for RTP streaming, where 49xxx = 49152 + twice the maximum number of channels purchased under the licensing agreement. For example, if 120 channels were purchased, 49xxx would be 49392.

If the UDP/RTP port range used by the HMP system conflicts with other RTP service, the following procedure describes how to configure HMP to use a different UDP/RTP port range:

1.Stop the system service.

2.Locate the .config file in the /usr/dialogic/data directory that matches the FCD/PCD files associated with your licensed configuration.
