HMP Software performs media processing tasks on general-purpose servers
without the need for specialized hardware. Media processing takes place on the host
processor. The software provides media services that can be used to build flexible,
scalable, and cost-effective next-generation IP media servers.
Dialogic HMP Software software supports two direct APIs: Dialogic
®
R4 APIs for media
processing and Dialogic
®
Global Call API for call control.
Dialogic HMP Software supports the industry-standard Session Initiation Protocol (SIP)
protocol for call control, with Real-time Transport Protocol (RTP) and Real-time Control
Protocol (RTCP) for media streaming and control over IP in various audio formats, video
formats, and fax formats.
Since Dialogic HMP Software is implemented as a software-only product, it can be
installed and upgraded like other software.
Dialogic HMP Software is available through a flexible licensing scheme. Dialogic HMP
Software media resources are provided via a license file, which contains authorization for
a combination of call control and media processing features. Customers may choose the
combination of resources they need for their solution, and obtain additional resources as
their system grows.
