The OpenScape Desk 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.
