Likely >99% of _humans_ dial phone numbers one digit at a time when they "dialing". That doesn't mean that the technology that establishes the actual communication link must continue to start beating a path for every new digit. 20 years ago the German Telekom still had mix of old mechanic phone switches and newer digital switches. If the equiment on your end supported and was using DTMF but the call was routed over old switches, you could listen to the clicking sounds from the old rotary hardware how the call was routed to its destination, long after you had finished "typing" the number on your DTMF phones keypad. > > I dunno about you, but it seems utterly unreasonable to demand that we > change the way we've been placing calls for the better part of a > century merely to avoid a few DNS lookups.

I'm all in favour of full backwards compatibility! For those that have come to love slow dialing, I'm all in favour of retaining the _ORIGINAL_ user experience, waiting for the rotary mechanical technique to complete its magic before the communication link is established. But since the telephone network backbone no longer provides this user experience, it needs to be emulated by all VoiP equipment that offers attachment of two-wire analogue phones. I'm sorry for my insensitivity to describe the enlighenting performance of the classical phone user experience by the VoiP equipment emulation as a "timeout" (preceding the instant connection setup with the full and final number). -Martin _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
