Table 3-35: Advanced Parameters Description

Determines whether the device accepts SIP calls received from only IP
addresses defined in the 'Tel to IP Routing' table (refer to ''Tel to IP
Routing Table'' on page 175) or 'Outbound IP Routing' table if
EnableSBC is set to 1 (refer to "Outbound IP Routing Table" on page
178). This is useful in preventing unwanted SIP calls or messages
and/or VoIP spam.
[0] Disable = device accepts all SIP calls (default).
[1] Enable = device accepts SIP calls only from IP addresses
defined in the 'Tel to IP Routing' table (or 'Outbound IP Routing'
table). The device rejects all calls from unknown IP addresses.
Note: Specifying the IP address of a Proxy server in the 'Tel to IP
Routing' table (or 'Outbound IP Routing' table) enables the device to
accept only calls originating from the Proxy server while rejecting all
other calls that don't appear in this table.
Enables filtering of Tel-to-IP calls when a Proxy is used (i.e.,
IsProxyUsed parameter is set to 1 -- refer to ''Proxy & Registration
Parameters'' on page 132).
[0] Don't Filter = device doesn't filter calls when using a Proxy.
(default)
[1] Filter = Filtering is enabled.
When this parameter is enabled and a Proxy is used, the device first
checks the 'Tel-to-IP Routing' table or 'Outbound IP Routing' table
before making a call through the Proxy. If the number is not allowed
(i.e., number isn't listed in the table or a call restriction routing rule of IP
address 0.0.0.0 is applied), the call is released.
Note: When no Proxy is used, this parameter must be disabled and
filtering is according to the 'Tel-to-IP Routing' table (or 'Outbound IP
Routing' table).
The Digit Delivery feature enables sending DTMF digits to the
destination IP address after the Tel-to-IP call is answered.
[0] Disable = Disabled (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: The called number can include several 'p' characters (1.5
seconds pause), for example, 1001pp699, 8888p9p300.
Enables the Digit Delivery feature, which sends DTMF digits (of the
called number) to the device's B-channel (phone line) after the call is
answered [line offhooked (FXS) or seized (FXO)] for IP-to-Tel calls.
[0] Disable = Disabled (default).
[1] Enable = Enable Digit Delivery feature for the device (two-stage
dialing).
