Summary:                    [patch] Caller ID support for UK (BT POTS lines)
Description: 
This is an experimental patch to add caller id support for UK POTS lines.

The zaptel side of the patch just adds a 2 second rolling buffer that the
userspace driver can interrogate.  As the caller ID information in the UK
is sent before the first ring the CID burst will be there rather than
within the ring data itself as on the Bell system.

The asterisk side of the patch just adds v23 support to fskmodem and grabs
the saved buffer and passes it through the callerid state machine.  

Selection of the UK caller id format is currently by a 'ukcallerid=yes'
line.  This should probably be broadened out into a generic CID selection
for things like DTMF, etc.  

At the moment I'm just encouraging testing... it seems to work for me but
haven't had much feedback yet.

I just 'ported' the patches to Asterisk-1.6.1-rc1 and dahdi-2.1.0.4 sent it
to Marc for publication here:
http://www.lusyn.com/resources/asterisk/usehist.htm

He emailed me today to confirm he's putting them up.

I was also going to take a look at the overhead issue as it seems sensible
to get this patch into a state to go into the main dahdi driver. Given the
tiny patch size it certainly seems that there's minimal 'bloat' at a code
level so maybe making the data structures dynamically allocated will
address any memory usage bloat concerns.
A dynamic approach would also allow the history approach to be selected by
those few of us who need it and minimise the overhead for others.
