Setting Description
Codec priority This setting specifies the codec priority for audio compression and
transmission. After changing the order of priority with the Up/Down buttons,
click on Reset codes.
NOTE: In a multicell setup, you must also go to the multicell page and click on
Reboot chain in order to update the handsets in the multicell installation.
Options: G.722; G.711A-law, �-law; G.726
NOTE:
With G.722 in the list, the codec negotiation algorithm is active. This causes
the handset setup time to be slightly slower than when G.722 is removed
from the list.
With G.722 as first priority, the number of simultaneous calls per base station
will be reduced from 10 (8) to 4 calls.
RTP packet size This setting specifies the packet size oered as preferred RTP packet size
during RTP packet size negotiation.
Default value: 20 ms
Secure RTP If enabled, RTP will be encrypted (AES-128) using the key negotiated via the
SDP protocol at call setup.
Default: Disabled.
Secure RTP Auth If enabled, secure RTP will use authentication of the RTP packages.
NOTE: With enabled SRTP authentication, a maximum of 4 concurrent calls
per base station is possible in both single-cell and multicell systems.
Default: Disabled.
SRTP Crypto Suites Supported SRTP Crypto Suite: AES_CM_128_HMA_SHA1_32
