As per Caleer ID spec. Caller ID info is tranmitted between first and second rings. This is to allow the phone to 'wake up' and receive the Caller ID information. If you were to pick up the phone right before it rang the first time or shortly after the first ring stopped you will not get caller id.

The phone *does* ring before the caller-id is available. In fact, it shoes some alternate message like "waiting for caller id info" right after the first ring and then changes to the real caller-id after the 2nd ring. -Dorn On Thu, Dec 23, 2004 at 03:44:14PM -0500, Steve Prior wrote: > Andrei (MPI) wrote: > > >richard wrote: > >>Asterisk also ring (so that all three of them are ringing), and then > >>someone can then choose which phone they want to answer? > > > > > >Hi Richard, > > > >Absolutely, you can do that with Asterisk.
