Select
Vocoders
72
in the order of preference from the drop down box. Depending on the RTP Mode that
you select in the VoIP Port parameters page (see
PBX Settings
tab), the availability
of Vocoders will change.
Following is the default list of Vocoders supported by NAVAN in the order of preference, i.e. 1st to 5th,
when the selected RTP Mode (in the VoIP Port parameters page) is Transcoding:
•
G.723
•
G.729 AB
•
GSM FR
•
G.711
Law
•
G.711 A - Law
However, when the selected RTP Mode (in the VoIP Port parameters page) is either RTP Relay or Direct
RTP, three more Vocoders can be selected from the list. These are as follows:
•
iLBC-30ms
•
iLBC-20ms
•
G.722
If you do not want to select any Vocoder, you can select the option 'None'. However, if all Vocoder
Preferences from 1 to 5 are set to 'None', incoming and outgoing calls will be blocked.
3.
If you selected G.723 codec as a Preferred Vocoder, select
G.723 Bit Rate
as: Bit Rate: 5.3 Kbps or 6.3
Kbps. Default: 6.3kpbs.
When G.723 is negotiated, the selected Bit Rate will be applied only when sending the RTP packets.
When receiving RTP packets from the remote end, both Bit Rates of G.723 will be accepted.
4.
Select the check box
Silence Suppression
to suppress the 'Silence' packets, and to allow only the Voice
packets through. NAVAN supports Silence Suppression for all Vocoders except GSM FR.
5.
Select the
DTMF Option
.
The DTMF option you select will determine how the DTMF digits will be sent over the IP Network, when a
DTMF digit is pressed.
NAVAN supports the DTMF options:
RTP (RFC 2833)
,
SIP Info
, and
In-Band
. Select the appropriate
option. Default: RTP (RFC 2833).
6.
If you have selected RTP (RFC 2833) as the DTMF Type, you must configure the value of
RFC 2833
Payload Type
. The RTP packets will be tagged as DTMF as per the set value. The value of RFC 2833
Payload Type can be set from 96 to 127.
72.
Vocoders are the various voice codecs used to compress the data in RTP packets for optimum use of bandwidth and better voice
quality.
