Parameter Description
Signaling DiffServ
[ControlIPDiffServ]
Defines the value of the 'DiffServ' field in the IP header for the signaling session.
The valid range is 0 to 63. The default value is 0.
IP Security
[SecureCallsFromIP]
No [0] = Gateway accepts all H.323 calls (default).
Yes [1] = Gateway accepts H.323 calls only from IP addresses defined in the Tel to IP
routing table. The gateway rejects all calls from unknown IP addresses.
For detailed information on the Tel to IP Routing table refer to Section
5.8.4.2 on page
74.
Recommended: When Gatekeeper is used, set this parameter to No; leaving the
Gatekeeper to determine whether to accept or reject H.323 calls.
Filter Calls to IP
[FilterCalls2IP]
Don’t Filter [0] = Disable the Filter Calls To IP service (default).
Filter [1] = Enable the Filter Calls To IP service.
If the Filter Calls To IP feature is enabled, then when a Gatekeeper is used, the gateway
first checks the TelIP routing table before making a call through the Gatekeeper. If the
number is not allowed (number isn’t listed or a Call Restriction routing rule, IP=0.0.0.0, is
applied), the call is released.
Enable Digit Delivery to Tel
[EnableDigitDelivery]
Disable [0] = Disabled (default).
Enable [1] = Enable Digit Delivery feature for MP-1xx/FXO & FXS.
The digit delivery feature enables sending of DTMF digits to the gateway’s port after the
line is offhooked (FXS) or seized (FXO). For IPTel calls, after the line is offhooked /
seized, the MP-1xx plays the DTMF digits (of the called number) towards the phone line.
Note 1: The called number can also include the characters ‘p’ (1.5 seconds pause) and
‘d’ (detection of dial tone). If the character ‘d’ is used, it must be the first “digit” in the
called number. The character ‘p’ can be used several times.
For example, the called number can be as follows: d1005, dpp699, p9p300.
To add the ‘d’ and ‘p’ digits, use the usual number manipulation rules.
Note 2: To use this feature with FXO gateways, configure the gateway to work in one
stage dialing mode.
Note 3: If the parameter ‘EnableDigitDeliveryl’ is enabled, it is possible to configure the
gateway to wait for dial tone per destination phone number (before or during dialing of
destination phone number), therefore the parameter ‘IsWaitForDialTone’ (that is
configurable for the entire gateway) is ignored.
Note 4: The FXS gateway sends Connect messages only after it finishes playing the
DTMF digits to the phone line.
EnableDigitDelivery2IP
[Enable Digit Delivery to IP]
Disable [0] = Disabled (default).
Enable [1] = Enable digit delivery to IP.
The digit delivery feature enables sending of DTMF digits to the destination IP address
after the Tel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 Setup 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).
Note: The called number can include several ‘p’ characters (1.5 seconds pause).
For example, the called number can be as follows: pp699, p9p300.
