Call Settings
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.
Dial Plan Prefix
Sets the prefix added to each dialed number.
