Dian Plan
FIRMWARE VERSION 1.0.6.8
Sets the time in which an incoming from PSTN call will stop ringing when not picked up.
Default is No. Use only if proxy supports 484 response. This parameter controls
whether the phone will send an early INVITE each time a key is pressed when a user
dials a number. If set to "Yes", an INVITE is sent using the dial-number collected thus
far. Otherwise, no INVITE is sent until the "(Re-)Dial" button is pressed or after about 5
seconds have elapsed. The "Yes" option should be used ONLY if there is a SIP proxy
configured and the proxy server supports 484 Incomplete Address response.
Otherwise, the call will likely be rejected by the proxy (with a 404 Not Found error).
Note: This feature is NOT designed to work with and should NOT be enabled for direct
IP-to-IP calling.
Sets the prefix added to each dialed number.
This allows users to configure the # key as the "Send" (or "Dial") key.
If set to "Yes", "#" will send the number. In this case, this key is essentially equivalent
to the "Dial" key.
If set to "No", the "#" key can be included as part of a number.
Dial plans work only for incoming calls from PSTN network. In case unconditional call
forward to VoIP is configured, dial plan feature will not work. In case of normal dialing

If using the 'hop on/hop off' feature, the dial plan rules affect only the last called number
(i.e. the number called after receiving dial tone from the ATA).
