That's what ATD would do on all modems I ever had or used, too. It was
only when I got an AT&T Paradyne Dataport that I found a modem that
specifically said it would dial a number using ATD, e.g. ATD5551212.

That's what I found would also work with the Zoom 2949L (Lucent chipset)
and it will dial a number using the same method as the old Paradyne
(e.g. ATD5551212). According to documentation on the old Paradyne, that
modem can recognize only certain letters of the alphabet as part of the
dialing string after ATDT or ATDP and "T" isn't one of them (with the
Paradyne, only 0-9, *, #, A, B, C, D can be dialed touch tone, and if
using pulse only 0-9 can be dialed). However, I've just tried this with
my Zoom 2949L (Lucent chipset) and it behaves just as your modem did.
In other words, if I do a string like this ATDP555T1212, it will dial
the first three digits (555) using pulse dialing and then the next four
(1212) using tone, but then I get a message from the phone company,
"We're sorry, your call did not go through. Will you please hang up and
try again?"
I think the switch at the CO doesn't like the call to be made using a
combination of pulse and tones. I suspect they require that if you set
up for pulse or for tone, you dial the whole number to complete the call
in the same mode. After that you could switch from pluse to tone to use
a automated entry system that requires tone input, for example, assuming
you had caused the modem to return to command mode by using ";" at the
end of the phone number. I haven't run into anything where I'd need to
do this in conjunction with using a modem, but someone might want to.
