Features
The new Dialogic
®
Conferencing API library supports the following features:
Asynchronous programming model support
This model enables multiple channels to be handled in a single process and supports
higher density conferencing solutions.
Support for conferees from multiple sources
Participants in a conference may come from a variety of sources, such as a voice
device and an IP media device. The software is designed for flexibility to grow and
support additional sources.
Conference bridging
Multiple conferences can be bridged together so that all parties (also called
conferees) in two or more established conferences can communicate with one
another.
Coach/pupil feature
Two selected parties can establish a private communication link within the overall
conference. The coach is a private member of the conference and is only heard by the
pupil. However, the pupil cannot speak privately with the coach.
DTMF digit detection
The application can determine whether a party has generated a DTMF digit.
Volume control
A conferee can adjust the output volume, either by API command or by DTMFs
detected on a conferee’s input leg.
DTMF tone clamping
This feature mutes dual tone multi-frequency (DTMF) tones heard during a
conference. Tone clamping applies to the transmitted audio going into the conference
and does not affect DTMF function. It can be enabled on a board, conference, or party
basis.
