I haven't heard much griping about the handling of incoming DTMF tones
in Skype, but considerable complaints about outgoing. If you search
for DTMF in Skype forums you'll find dozens of posts about it. Here's a
typical example:

They work about half the time from my Mac when I call from abroad to
pick up voice mail.

No, you need to be attacked for pretending Voip is a replacement for
cellular, instead of a (limited-use) augmentation.

No, But it works 800-1100 times farther away from my wireless router ;-)

My T-Mobile phone shows full signal in my basement. so YMMV. It
generally sounds better than Skype on my two year old Celeron laptop and
1.5mbps DSL connection as well.

Fair enough.

Seems like they'd do DTMF generation at the point where it enters the
POTS, not inside your computer. Sure would save on the data stream
bandwidth going out just sending numbers instead of voice data converted
tones.

I've checked Skype voicemail hundreds of times from my cellphone through
Vox on my computer, a double set of conversions across the POTS. It
seemed to work fine.

Well, we have to find some nit to pick to trash it, eh?

You are very lucky to have a tower in your yard. Most cellular customers
walk around to one of their house hotspots where the damned phone will
connect through the poor signal and multipath reflections to use it.

Some would kill to have full bars in a basement!

Larry, we've had the CDMA / multipath discussion before...

Didn't you learn something about CDMA last time...?
