[Asterisk-Users] problem with SIP configuration AND EXTENSION.

>Apr 11 08:59:27 NOTICE[81926]: chan_sip.c:5568 handle_request: Registration from '<sip:phone at 192.168.0.6>' failed for '192.168.0.6'

Are you sure your phone isn't registering?   These errors aren't related to your grandstream.  Do a "sip show peers" at the Asterisk CLI and see if it shows your phone registered.

Take this line out.  You don't need it.  That's only for remote SIP providers.  You're telling your * box to register with itself.  And obviously bad things are happening!
