ip telephony region
Description
Regional settings are used to adjust the voice port properties to the PSTN system or the PBX. For
example, to detect hang-up from line, there has to be correct regional setting (correct
busy-tone-frequency and busy-tone-cadence). Without that, detect-cpt parameter the voice port has
to be enabled.
Property Description
name (name) - name of the regional setting
busy-tone-cadence (integer: 0..30000; default: 500,500) - busy tone cadence in ms
• 0 - end of cadence
busy-tone-frequency (integer: 20..2000 | integer: -24..6; default: 440x0) - frequency and volume
gain of busy tone, Hz x dB
data-access-arrangement (australia | france | germany | japan | uk | us; default: us) - ring voltage,
impedance setting for line-jack card
dial-tone-frequency (integer: 20..2000 | integer: -24..6; default: 440x0) - frequency and volume
gain of dial tone, Hz x dB
dtmf-tone-cadence (integer: 0..30000; default: 180,60) - Dual Tone Multi Frequency tone cadence
in ms
• 0 - end of cadence
dtmf-tone-volume (integer: -24..6; default: -3,-3) - Dual Tone Multi Frequency tone volume in dB
ring-tone-cadence (integer: 0..30000; default: 1000,2000) - Ring tone cadence in ms
• 0 - end of cadence
ring-tone-frequency (integer: 20..2000 | integer: -24..6; default: 440x0) - frequency and volume
gain of busy tone, Hz x dB
Notes
To generate a tone, frequency and cadence arguments are used. The dialtone always is continuous
signal, therefore it does not have the cadence argument. In order to detect dialtone, it should be at
least 100ms long.
There are 10 pre-defined regions, which can not be deleted (but may be changed)
Audio CODECs
ip telephony codec
Description
CODECs are listed according to their priority of use. The highest priority is at the top. CODECs can
be enabled, disabled and moved within the list. When connecting with other H.323 systems, the
protocol will negotiate the CODEC which both of them support according to the priority order.
The hardware codecs (/hw) are built-in CODECs supported by some cards.
The choice of the CODEC type is based on the throughput and speed of the network. Better audio
quality can be achieved by using CODEC requiring higher network throughput. The highest audio
