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 is NOT designed to
work with and should NOT be enabled for direct IP-to-IP calling.
