[Asterisk-Users] Registration Fail

[Miguel]

I have many ATA devices, some ATA186, some SPA2000 and some Handytone, and
I'm verifing an strage behavion on the *, many times a day they have
problems with registration and show the messages below:

Oct 28 11:04:02 NOTICE[1087720240]: chan_sip.c:7493 handle_request:
Registration from '2007 <sip:2007 at 192.168.199.4>' failed for
'192.168.199.254'
Oct 28 11:08:34 NOTICE[1087720240]: chan_sip.c:7493 handle_request:

The first two are internal users and the other is a external user, but the
same problem for all.

At the same time tethereal show me this:
