Accept SIP Trust Server Only

Accept SIP trust server only enables the DECT IP phones to only accept the SIP message from
your SIP server and outbound proxy server. It can prevent the phone receiving ghost calls from
random numbers like 100, 1000, etc. To stop this from happening, you also need to disable
allow IP call feature. For more information on allow IP call, refer to
