[Asterisk-Users] Caller ID with BT CD50

[Robinson Tim-W10277]

Presumably this can then be modified for DTMF caller ID by those in NL, Brazil etc?

I will give it a go soon.

Thanks
Tim

I keep rolling buffer of the last couple of seconds of the incoming 
audio, so when the ring is detected the chan_zap driver can grab this 
and feed it to the callerid processing routines.

If it's necessary to assign copyright to digium then there's no problem 
doing that.

At the moment there's a rather lame 'ukcallerid=yes' command... it needs 
something better certainly but there's plenty of time to get that stuff 
right.

The current patches are at http://www.nodomain.org/asterisk/

Ugh. V23 after first ring...  It also matters of course if the cable co. 
has changed the wire data format - you might be able to grab the data 
but then not be able to make any sense of it..
