Web Parameter Name
Valid Range and Description
DisableAutoDTMFMute Enables / disables the automatic mute of DTMF digits when out-of-band
DTMF transmission is used.
0 = Auto mute is used (default).
1 = No automatic mute of in-band DTMF.
When ‘DisableAutoDTMFMute=1’, the DTMF transport type is set according
to the parameter ‘DTMFTransportType’ and the DTMF digits aren’t muted if
out-of-band DTMF mode is selected (’TxDTMFOption =3, 5 or 6’). This
enables the sending of DTMF digits in-band (transparent of RFC 2833) in
addition to out-of-band DTMF messages.
Usually this mode is not recommended.
3xxBehavior Determines the gateway’s behavior when a 3xx response is received for an
outgoing INVITE request. The gateway can either use the same call
identifiers (CallID, branch, to and from tags) or change them in the new
initiated INVITE.
0 (forward) = Use different call identifiers for a redirected INVITE message
(default).
1 (redirect) = Use the same call identifiers.
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 Proxy is not responding (according to the Proxy keep alive mechanism)
or if there is a failure in the network, and if fallback isn’t enabled
(IsFallbackUsed=0), 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). Note
that 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 Tel
Æ
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 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).
The called number can include several ‘p’ characters (1.5
seconds pause).
For example, the called number can be as follows: 1001pp699,
8888p9p300.
