Dead wrong. Every cellular switch in the U.S. is connected to the local network just like a PBX. No phone company is currently offering SS7 (the prerequisite for Caller ID) as a method of connection for PBXs. This means that where there is Caller ID, the number which will appear is _not_ the cellular number, but rather the number assigned to one of the DoD trunks. In fact, when I call the New England Telephone operator in Boston from a NYNEX or Southwestern Bell cellular phone, the operator doesn't have the cellular number. >Further, I'm sure the cellular switch RECEIVES the Caller*ID >info just fine as well. Nope. Sorry. Again, cellular switches are connected without the benefit of SS7, and have no way to receive Caller ID info, which can _only_ be passed on lines (not trunks). >I don't think there's any provision in the cellular standard for text >information to be passed to the remote during call setup. Correct, and it probably won't be added to the standard. /john

In article <4329@accuvax.nwu.edu> it is written: >>There's no reason (none at all), why cellular phones shouldn't >>generate Caller*ID (eg. the person being called FROM a cellular phone >>would get correct Caller*ID displayed on his box), as the 'switch' >>part of a cellular system is pretty much a standard model. Upon checking here in the Miami, Florida area, where caller ID is currently under consideration by the PSC, I am told there will be NO caller ID available on calls made FROM cellular phones or Pay phones. bsherman@mthvax.cs.miami.edu | bsherman@pro-exchange | MCI MAIL: BSHERMAN >> Miami's Big Apple - 305-948-8000 - 24 hours - 300/1200 - PCP'able << >> Oldest Apple support board in Southeast.

Not even 911 knows who you are. I once was having problems dialing a long distance call, and the AT&T operator said that they can't provide call completion assistance for direct dial calls from cellular since they don't know who you are. There was a posting in the Digest a couple of months ago that mentioned that one of the new Motorola hand-helds had a Caller ID display built into it. I'm not sure I understand how this would work, considering the current protocols and MTSO-BOC connections. Anyone know?
