- When I am using my IBX work phone and someone calls, I hear a tone,
- and the caller hears "rrrringg-BOOP rrrringg-BOOP ..." I know that at
- least some callers from outside our switch hear the BOOP, but I'm
- wondering how far it extends. I had always thought that the ring
- signal was generated locally, and if that's true, then my switch must
- be passing some signal for "phone in use, but call waiting ringing,"
- to which the caller's switch generates the "rrrringg-BOOP." I think
- it would be a nice thing to have nationwide so I knew the difference
- between a ring/phone-on-hook and a ring/interrupting-a-call.
-
- Can someone in the know fill me in on the technical details of
- "rrrringg-BOOP" ? We own our own switch here, but I don't know what
- kind it is.

- [Moderator's Note: Actually, if you listen closely, when the called
- party answers you will hear a certain kind of click on the line if you
- interuppted them on call waiting which you won't hear if you did not.
- A few PBXs using Direct Inward Dialing have the special ring signal
- you describe when cal-waiting interupts an extension user. PAT]
