Codec Preferences

If Silence suppression is activated, the transmission of data packets is suppressed on no con-
versation, that is, if the user doesn't speak.
The OpenStage phone provides the codecs G.711, G.722, and G.729. When a SIP connection
is established between two endpoints, the phones negotiate the codec to be used. The result
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, 20ms, 30ms, 60ms or to automatic detection.
