I am getting the same with a Grandstream HT-486, but only after going thru the process of connecting to a STUN server. The first register attempt does not contain a "Authorization: DIGEST" line in the packet, but if I reboot it from it's config webpage it will send the auth credentials and registers successfully.

I have sent a request to Grandstream support and will post their solution.

Hi, I am getting the same 401 unauthorized error message. I am using pingtel pbx and trying to configure the grandstream phone Budgte tone-100. Would have any ideas as how to fix this problem. Thanks, Sonal
