asterisk users - Aug 2003 - Does Wildcard x100p support BT Caller ID in UK?

Hi all,

I can't seem to find any info on this anywhere on the web, except that BT
caller ID doesnt use the standard bellcore system in use in the US. So, if
anyone here in the UK is onlist and using the x100p successfully, please let
me know.


TIA,
Dave

We use it, but with no caller id.

I don't have the answer to your question, I just know that it doesn't
work in the Netherlands. That does not mean it will not work in the UK,
as UK uses a different standard. While searching for specs I found that
in the UK there's different caller-id standards in use amongst the
different telco's.
I'd suggest you locate the exact protocol spec for BT caller ID. If it
is a dialect of FSK, there's a fair chance that it could be made to
work.

Unfortunately the present x100p driver code will not decode the callerid for 2 
reasons

1) the UK protocol is different to the US system. 
I have downloaded the specs and coding it would not be too difficult.

2) in the US the callerid is sent between the first and second rings. In the 
UK the callerid is sent before the first ring. 
I have been unable to determine if we can get a zaptel event when a line 
reversal is received which happens before the UK callerid is sent. Without 
this function or continuously monitoring the line for the tones we don't
know
when to enter the callerid routine.  

Apart from the callerid the x100p works well in the UK but without callerid I 
can't implement lots of things I would like to do.
