Table 5-11: DTMF and Dialing Parameters
Parameter Description
Max Digits in Phone Num
[MaxDigits]
Defines the maximum number of collected destination number digits that
can be received (i.e., dialed) from the Tel side when Tel-to-IP overlap
dialing is performed. When the number of collected digits reaches the
maximum, the gateway uses these digits for the called destination number.
The valid range is 1 to 49. The default value is 30.
Notes
1
:
Digit Mapping Rules can be used instead.
Note 2: Dialing ends when the maximum number of digits is dialed, the
Interdigit Timeout expires, the '#' key is dialed, or a digit map pattern is
matched.
Inter Digit Timeout for
Overlap Dialing [sec]
[TimeBetweenDigits]
Defines the time (in seconds) that the gateway waits between digits that
are received (i.e., dialed) from the Tel side when Tel-to-IP overlap dialing
is performed . When this inter-digit timeout expires, the gateway uses the
collected digits for the called destination number.
The valid range is 1 to 10 seconds. The default value is 4 seconds.
Declare RFC 2833 in
SDP
[RxDTMFOption]
Defines the supported Receive DTMF negotiation method.
ƒ
[0]
No = Don't declare RFC 2833 telephony-event parameter in SDP.
ƒ
[3]
Yes = Declare RFC 2833 telephony-event parameter in SDP
(default).
The gateway is designed to always be receptive to RFC 2833 DTMF relay
packets. Therefore, it is always correct to include the 'telephony-event'
parameter as a default in the SDP. However some gateways use the
absence of the 'telephony-event' from the SDP to decide to send DTMF
digits in-band using G.711 coder. If this is the case, you can set
RxDTMFOption to 0.
