ppp won't dial out

[Jorge Santos <jsf@dep3.fciencias.unam.mx>]

Hello, the phone compay provides me with an answering machine of
sorts, such that when I have a message the phone, instead of giving
me the usual dial tone gives me something like a busy tone, well, it
is broken now, and I got this busy tone at all times, it shouldn't be
such big of a deal tho, because I can still dial out.

Now, the problem is the modem refuses to dial out because it doesn't
get a dial tone.  Any suggestions on how to make it dial out even when
there's no dial tone?

Greetings,
