One sounds one way, another some other way. PAT] Well, I can understand the slight differences in tones, etc. But something rather odd occurred today: I dialed a number in 703, and instead of receiving the standard U.S. single ring, I received a non-US double ring. I realize that the equipment can produce whatever it wants (indeed, our PBX uses double-ring to indicate outside calls, but the outside caller still hears the US single ring). Isn't there some sort of BellCore standard that says that the CO has to produce a US single ring?

I've gotten so I can tell immediatly when my call is (going to be) picked up by an answering service to which the called party has forwarded his number. (Or if the number I dialed is a DID line terminating in an answering service. Sometimes voice mail DID lines ring that way also. PAT]
