Parameter Description
Signaling DiffServ
[ControlIPDiffServ]
Defines the value of the 'DiffServ' field in the IP header for SIP messages.
The valid range is 0 to 63. The default value is 0.
IP Security
[SecureCallsFromIP]
No [0] = Gateway accepts all SIP calls (default).
Yes [1] = Gateway accepts SIP 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
75.
Note: Specifying the IP address of a Proxy server in the Tel to IP Routing table enables
the gateway to only accept calls originating in the Proxy server and rejects all other
calls.
Filter Calls to IP
[FilterCalls2IP]
Don’t Filter [0] = Disabled (default)
Filter [1] = Enabled
If the filter calls to IP feature is enabled, then when a Proxy is used, the gateway first
checks the TelIP routing table before making a call through the Proxy. 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 IP
[EnableDigitDelivery2IP]
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 TelIP 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).
Note: The called number can include several ‘p’ characters (1.5 seconds pause).
For example, the called number can be as follows: pp699, p9p300.
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 IPTel 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 ‘EnableDigitDelivery’ 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 200 OK messages only after it finishes playing the
DTMF digits to the phone line.
