Sorry, I didn't mean to post that again. My question is: Is the sip registration server automatically the trusted server or is the trusted server set somewhere else? I know that in some phones there is a separate setting for the trusted servers. Also at 2 sites when I upgraded to the firmware you suggested and set the phones as you suggested either the phone would not register or it would register and have one sided calls. When I would revert to the older firmware these problems went away but that defeats the fix. Also at one of those sites I continued to have ghost calls after the upgrade that is why I asked the above question.
