[asterisk-users] Incoming calls from Andrews & Arnold failing to authenticate

I have service with both VoIPtalk.org and Andrews & Arnold (aa.net.uk).
VoIPtalk calls are unauthenticated and reach me fine, but Andrews &
Arnold calls are authenticated. The last call I successfully received
was on Tuesday afternoon. Initially, A&A were for some odd reason not
sending calls to my server, but that has been resolved. The problem now
is that the calls fail to authenticate, and are therefore rejected -
error 403 is presented to them, and I see this in Asterisk's console: 

[Apr 23 11:53:19] NOTICE[27398][C-00000004]: chan_sip.c:25535
handle_request_invite: Failed to authenticate device "XXXXX XXXXXX"
<sip:XXXXXXXXXXX at voiceless.aa.net.uk>;tag=2016042311531900001

I have checked that the username and password in my config agree both
ends, and have even tried changing them.

The bulk of my calls come in on A&A, so I am obviously trying to find
out what has gone wrong. No-one else is seeing any problem. What do I
need to do to track this down?
