You can set phone to only accpet calls from your sip server through autoprovision:

Parameter:
account.1.sip_trust_ctrl = 1

Or you can upgrade phone to V73 and enable this option under Account-> Advanced interface.

Regards,
James

I have upgraded to V73 and enabled the option. It appears to be working. Thank you very much for your time and assistance. I highly appreciate it.
