What About HMP?
The LumenVox Speech Platform offers very limited compatibility with Dialogic's Host Media Processing
technology. The Platform's HMP compatibility is primarily intended to be used for development purposes
and is not intended for use in production systems. It is not complete and is missing certain key HMP features.
LumenVox certifies only certain releases of the Speech Platform to work with specific versions of the
HMP package. You may contact technical support for more information about which Platform releases work
with which HMP versions.
If you have a project that would require full HMP support with the Speech Platform, please contact
LumenVox sales to discuss it.
