[Asterisk-Users] Caller ID with BT CD50

[Tim Robinson]

Tony -
This sounds great.  Are you monitoring the line constantly for the 
inbound caller ID or are you somehow detecting the polarity reversal?

Look forward to trying out your solution!  I think you will have a lot 
of happy bunnies here in Blighty, as the current lack of caller ID on 
our BT lines is the thing that makes Asterisk less viable for most home 
users....

If it works and is stable, will you disclaim your code so that it will 
get merged into the main CVS?  There should probably be a couple of 
settings in zapata.conf for the caller id coding scheme to be used for 
each card

calleridtones = (V23, Bell or DTMF)
calleridarrives = (afterring, afterrev, etc)

since a lot of people here in UK have a line from BT and a cable co 
line, where the cable co either uses Bellcore after 1st ring, or V23 
after 1st ring. So you need to be able to chose the method for each 
line. What a mess, eh?
