Parameter Description
Enable Digit Delivery to IP
configure voip > sip-definition settings
> digit-delivery-2ip
[EnableDigitDelivery2IP]
Enables the Digit Delivery feature whereby DTMF digits are
sent to the destination IP address after the Tel-to-IP call is
answered.
 [0] Disable (default).
 [1] Enable = Enable digit delivery to IP.
To enable this feature, modify the called number to include
at least one 'p' character. The device uses the digits before
the 'p' character in the initial INVITE message. After the call
is answered, the device waits for the required time (number
of 'p' multiplied by 1.5 seconds), and then sends the rest of
the DTMF digits using the method chosen (in-band or out-of-
band).
Note:
 For the parameter to take effect, a device reset is
required.
 The called number can include several 'p' characters (1.5
seconds pause), for example, 1001pp699, 8888p9p300.
Enable Digit Delivery to Tel
configure voip > sip-definition settings
> digit-delivery-2tel
[EnableDigitDelivery]
Global parameter enabling the Digit Delivery feature, which
sends DTMF digits of the called number to the device's port
(analog)/B-channel (digital) (phone line) after the call is
answered (i.e., line is off-hooked for FXS, or seized for FXO)
for IP-to-Tel calls.
You can also configure the functionality per specific calls,
using Tel Profiles (TelProfile_EnableDigitDelivery). For a
detailed description of the parameter and To configure the
functionality in the Tel Profiles table, see ''Configuring Tel
Profiles'' on page 459.
Note: If the functionality is configured for a specific Tel
Profile, the settings of the global parameter is ignored for
calls associated with the Tel Profile.

[ReplaceNumberSignWithEscapeChar]
Determines whether to replace the number sign (#) with the
escape character (%23) in outgoing SIP messages for Tel-
to-IP calls.
 [0] Disable (default).
 [1] Enable = All number signs #, received in the dialed
DTMF digits are replaced in the outgoing SIP Request-
URI and To headers with the escape sign %23.
Note:
 The parameter is applicable only if the parameter
IsSpecialDigits is set 1.
 The parameter is applicable only to analog interfaces.
Special Digit Representation
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > special-
digit-rep
[UseDigitForSpecialDTMF]
Defines the representation for ‘special’ digits (‘*’ and ‘#’) that
are used for out-of-band DTMF signaling (using SIP
INFO/NOTIFY).
 [0] Special = (Default) Uses the strings ‘*’ and ‘#’.
 [1] Numeric = Uses the numerical values 10 and 11.
[ISDNKeypadMode]
Enables the device to send DTMF digits received in the
called party number from the IP side, as Keypad facility IE in
ISDN INFORMATION messages to PSTN.
 [0] Don’t send = (Default) All digits are sent as DTMF to
