indication is modiÞed to be RING:1234567. This is called the
concatenated
format.
The second format is a Tag = Value pair, where the only supported
tag is NMBR. The same example would return the string
NMBR = 1234567 on its own line after the Þrst RING indication.
A query may be sent during ringing that returns the calling line ID
information. This feature is independent of the delivery enable
feature.
