Web Parameter Name
Valid Range and Description
MaxActiveCalls
[Max Number Of Active Calls]
Defines the maximum number of calls that the gateway can have active at the
same time. If the maximum number of calls is reached, new calls are not
established.
The default value is max available channels (no restriction on the maximum
number of calls). The valid range is 1 to 240.
MaxCallDuration
[Max Call Duration]
Defines the maximum call duration in minutes. If this time expires, both sides
of the call are released (IP and Tel).
The valid range is 0 to 120. The default is 0 (no limitation).
EnableBusyOut
[Enable Busy Out]
0 = Not used (default)
1 = Enable busy out
If Busy out is enabled, all E1/T1 trunks are automatically put out of service by
sending a remote alarm (AIS) or Service Out message for T1 PRI trunks that
support these messages (NI-2, 4/5-ESS, DMS-100 and Meridian), due to one
of the following scenarios:
• Physically disconnected from the network (i.e., Ethernet cable is
disconnected).
• The Ethernet cable is connected, but the gateway can't communicate with
any host. Note that LAN Watch-Dog must be activated
(EnableLANWatchDog = 1).
• The gateway can't communicate with the gatekeeper/proxy (according to
the Proxy keep-alive mechanism) and no other alternative exists to send
the call.
Note: The Busy out behavior varies between different protocol types.
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 TelÆIP 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: 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).
Note: For incoming IPÆTel 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.
