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).

direct IP-to-IP calling.
