You need to ask your BT contact how many callerid digits they expect. 
A common configuration is the same number of digits as are given to you 
for DDI. Also you will often need prilocaldialplan=unknown for EuroISDN. 
This means the number is just digits in the form agreed to by you and 
your telco which is what is normally used for outgoing number presentation 
for EuroISDN.

Again, check with your BT contact:
 * verify that the line is set to accept calling number identification
 * the expected "Type Of Number" and "Numbering Plan" for the id
 * the expected number of digits to send.
