Description
Obsolete parameter, use PremiumServiceClassControlDiffServ instead.
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, see
Table.
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.
Do notFilter [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 Tel IP routing table before making a call through
the Proxy. If the number is not allowed (number is not listed or a Call
Restriction routing rule, IP=0.0.0.0, is applied), the call is released.
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 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.
