phone connected to the FXS port.
Ring Timeout
Default value is 60 Sec. Incoming call will stop ringing when not picked up given a
specific period of time.
Delayed Call Forward
Wait Time
Default value is 20 seconds. In case this feature activated using * codes (*92 code),
the call will be forwarded after this preconfigured amount of time.
No Key Entry Timeout
Default is 4 seconds. Dialing process is completed and outgoing call is initiated if no
key entry occurs during this preconfigured interval.
Early Dial
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 if the user forgets to press the ―Re-Dial‖ button.
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).
This feature does NOT work with and should NOT be enabled for direct IP-to-IP calling.
Dial Plan Prefix
Sets the prefix added to each dialed number.
Use # as Dial Key
Default is Yes. It 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‖, this ―#‖ key can be included as part of number.
