Codec Preferences

If Silence suppression is activated, the transmission of data packets is suppressed on no con-
versation.
The OpenStage phone provides the codecs G.711, G.722, and G.729. When an HFA connec-
tion is established between two endpoints, the phones negotiate the codec to be used. The re-
sult of the negotiation is based on the general availability and ranking assigned to each codec.
The administrator can allow or disallow a codec as well as assign a ranking number to it.
The Packet size, i. e. length in milliseconds, of the RTP packets for speech data, can be set
to 10ms or 20ms or to automatic detection.
