I have a Fanvil X3S that I was able to provision successfully with Direct SIP (STUN - remote) provisioning method. However every time I power cycle the phone it does not register. The line status reports a 404 or a timeout. If I go back into the phone web interface and replace the password with the password in the authentication section of the General tab on the extension the phone registers immediately. Reboot the phone and I have to start all over. I did download the lastes 3CX firmware file x3s2.04.3496.z and applied it before starting. Any suggestions would be appreciated.
