[comp.dcom.telecom] How to route LD call not changing LD carrier?

uri@uunet.uu.net (07/07/89)

Hello!

Sorry, I've seen somebody's poster on a similar question, but it's gone (:-)...

I want to know codes, which allow me to route my long-distance calls through
various LD companies (I'm going to try MCI and US Sprint, not saying about AT&T)As far as I know one should just dial five digits before the actual number - and
this way the call will be sent to a proper router.

Questions:
		1) What are the codes for AT&T, MCI, US Sprint (and others, if
		   they exist)?

		2) Where should I put that code? The # is: 1-xxx-yyy-yyyy
		   Where the code should be placed - before 1, after 1 but
		   before xxx?

Thanks to everybody who answers (without flames, I mean!).

Uri.

[Moderator's Note: The three main codes are: MCI = 10222; Sprint = 10333;
AT&T = 10288. There are many others; not all long distance carriers work
in all parts of the country. Consult the long distance carrier of choice
and see if they accept incoming traffic in your community. As for the
placement of the codes, if the carrier chosen is the default carrier for
your line, then you *do nothing*. Just dial the call normally. If you wish
to route the call to one of the other carriers, dial their code first, and
then the long distance number. For example, to call 1-310-555-2368 using
Sprint, you would dial 10333-1-310-555-2368. To dial it via MCI you would
enter 10222-1-310-555-2368.  Maybe one of the readers will send you a
complete list of carrier codes; you sort them out.  PT]
