Asterisk - UK callerid

["UKHA" <ukha@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

since there's been recent flurry of interest in asterisk thought you uk lot
might be interested in:

"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."
