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 collect

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
