There seem to be two major sources of billing problems. One is that each participant in placing a call wants to make money off the call. The other is that there is no billing protocol other than looking up data in one's own tables and guessing how much to charge based on the number called. Does anyone know if there are billing protocols in ISDN that would allow an intelligent instrument and/or a service provider know the cost of a call as it is being placed? Full name: Bob Frankston

I assume the question being asked is "would the D-channel support automatic call cost information?" Not really. The types of messages which go through the D-channel are more along the lines of call service requests (i.e. setup, connect, disconnect, release) and acknowledgements. (There are some neat extensions, though.) It is not well suited for this sort of thing. However, there is nothing which prevents your local carrier from providing you such a service. You would need some intelligence built into your telephone so that it would go out and inquire the carrier's database for billing information, and then proceed to connect the call. -- Chip Rosenthal chip@vector.UUCP | I've been a wizard since my childhood.
