CODEC
PRIORITY
Disabled Default disabled.
By enabling the system codec, priority during incoming call is
used instead of the calling party priority.
E.g. If base has G722 as top codec and the calling party has a
law on top and G722 further down the list, the G722 will be
chosen as codec for the call.
DTMF
SIGNALLING
RFC 2833 Conversion of decimal digits (and ‘*’ and ‘#’) into sounds that
share similar characteristics with voice to easily traverse
networks designed for voice
SIP INFO: Carries application level data along SIP signaling
path (e.g.: Carries DTMF digits generated during SIP session
OR sending of DTMF tones via data packets in the same
internet layer as the Voice Stream, etc.).
RFC 2833: DTMF handling for gateways, end systems and RTP
trunks (e.g.: Sending DTMF tones via data packets in
different internet layer as the voice stream)
Both: Enables SIP INFO and RFC 2833 modes.

G.711U

G.726
G.722
G.729
OPUS
BV32
Defines the codec priority that Base stations use for audio
compression and transmission.
Possible Option(s): G.711U, G.711A, G.726, G.722, G.729,
OPUS, BV32
Note: Modifications of the codec list must be followed by a
“reset codes” and “Reboot chain” on the multipage to
change and update handsets.
Note: With G.722 as priority, the number of simultaneous
calls per Base station will be reduced from 10 (8) to 4 calls.
With G.722 in the list, the codec negotiation algorithm is
active causing the handset (phone) setup time to be slightly
slower than if G.722 is removed from the list. Furthermore, it
will reserve audio resources to be able to handle the possible
G722 call and thus, the maximum number of possible
narrowband calls will be reduced by one extra.
Note: To use G.729 and OPUS, add on DSP module must be
installed in all Base stations. Contact your local dealer for
price information.
