Firs t digit
timer
parameter after offhook, the gateways will consider that the subscriber
has given up the call and prompt to hang up in busy tone. Unit: second;
Default value: 12 seconds.
Inter-digit
timer
dialing the last number key to the set time by this parameter, the
gateways will consider that the subscriber has ended dial-up and call out
the dialed number. Unit: second; Default value: 12 seconds.
Critical digit
timer
This parameter is used with the "x.T" rule set in dialing rules. For
example, there is "021.T" in the dialing rules table. When a subscriber
this parameter (eg. 5 seconds), the gateways will consider that the
subscriber has ended dial-up and call out the dialed number 021.
Unit: second; Default value: 5 seconds.
Codec
Codecs methods supported by the gateways include G729A/20,
G723/30, PCMU/20, PCMA/20, iLBC/30 and GSM/20 (as shown in
table 2-5). This parameter must be set due to no default value.
Several encoding methods can configure in this item at the same time,
platform in the order from front to back when configuring the codec
methods
Hook-flas h
handle
The gateways provide the following processing modes after detecting
hook flash from subscriber terminals: processing the hook flash
internally; transmitting the hook flash to platform with RFC 2833, and
transmitting the flash-off to platform with SIP INFO.
DTMF method
Transmission modes of DTMF signal supported by the gateways include
Audio, RFC 2833 and SIP INFO. The default value is Audio.
Audio: DTMF signal is transmitted to the platform with sessions;
SIP INFO: Separate DTMF signal from sessions and transmit it to the
platform in the form of SIP INFO messages;
RFC 2833: Separate DTMF signal from sessions and transmit it to the
platform through RTP data package in the format of RFC2833.
2833 pay load
ty pe
value of 2833 payload type is 100. The effective range available: 96 ~
127. This parameter should match the setting of far-end device (eg.
platform).
DTMF on-time
This parameter sets the on time (in ms) of DTMF signal sent from FXO
port. The default value is 100 ms. Generally, the duration time should be
set in the range of 80 ~ 150 ms.
