Timeout
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.
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. 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.
Dial Plan Prefix Sets the prefix added to each dialed number.
Use # as Dial key 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.
