communication.

Select the value according to the local Telco standard where the GXW42XX is
installed.
Please refer to the pull down list to select.
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.
