Valid Range and Description
EnableDigitDelivery2IP
[Enable Digit Delivery to IP]
0 = Disabled (default).
1 = Enable digit delivery to IP.
The digit delivery feature enables sending of DTMF digits to the destination
IP address after the Tel
Æ IP call was answered.
To enable this feature, modify the called number to include at least one ’p’
character.
The gateway uses the digits before the ‘p’ character in the initial INVITE
message. After the call was answered the gateway waits for the required
time (# of ‘p’ * 1.5 seconds) and then sends the rest of the DTMF digits
using the method chosen (in-band, out-of-band).
The called number can include several ‘p’ characters (1.5
seconds pause).
For example, the called number can be as follows: 1001pp699,
8888p9p300.
EnableDigitDelivery
[Enable Digit Delivery to Tel]
The digit delivery feature enables sending of DTMF digits to the gateway’s
B-channel after the call is answered.
0 = Disabled (default).
1 = Enable Digit Delivery feature for gateway (two stage dialing).
For incoming IP
Æ
Tel calls, if the called number includes the
characters ‘w’ or ‘p’, the gateway places a call with the first part
of the called number, and plays DTMF digits after the call is
answered. If the character ‘p’ (pause) is used, the gateway
waits for 1.5 seconds before playing the next DTMF digit. If the
character ‘w’ is used, the gateway waits for detection of dial
tone before it starts playing DTMF digits. The character ‘w’ can
appear once in the called number, and must precede any ‘p’
character. The ‘p’ character can appear several times.
For example: if the number ‘1007766p100’ is defined as the
called number, the gateway places a call with 1007766 as the
destination number, then, after the call is answered, it waits for
1.5 seconds and plays the rest of the number (100) as DTMF
digits.
Other examples: 1664wpp102, 66644ppp503,
7774w100pp200.
