FWIW: I once had a nasty DSL filter that broke polarity reversal
detection.

I had problems with my (old) phone ringing briefly at some stage, so I
experimented a little.

ah. Do you have callerid from BT (bt line?). I signed up for something
called BT Privacy or so which is free and gives you callerid. 
If you turn on logging (debug) on the sipura it'll log the received
callerid via syslog. Also helpful to check under info "Last seen number"
or so.
