"User=Phone" parameter will be attached to the "From header" in the SIP

needs to be selected.
SIP Registration This parameter controls whether the GXW40XX needs to send REGISTER messages to
the proxy server. The default setting is "Yes".
Default is No. If set to "Yes", the SIP user's registration information is cleared on reboot.
Unregister on Reboot
Default is No. If set to "Yes," user can place outgoing calls even when not registered (if

Any port, member of a Hunting Group that is not registered with a SIP account, will be
able to place outbound calls using the SIP credentials of the primary Hunting Group port.

able to place outbound calls using the SIP account of port 1, even if Outgoing Call
