Dear Andre Klapper,

I can confirm this bug and describe it better.

Here is some additional information:

1. GrandCentral is simply a SIP service by Google. I would think that a
developer of a SIP app, or Nokia at least, would be aware of that. FYI, I have
never tried it.

2. This problem has existed since OS2008, it did not occur in OS2007.

3. The problem is, as kimitake reported, that DTMF simply doesn't work AT ALL
in OS2008 with SIP calls once the call has been initiated.

4. The DTMF problem makes the Internet Call application worthless for any kind
of IVR (interactive voice response) call. Since SIP support is why I purchased
my tablet, that makes my tablet worthless for me, unless I use Skype for IVR
calls needing DTMF (which are MOST of my calls).

5. SkypeOUT calls cost me money.  I shouldn't have to use Skype since I'm
already paying for SIP service. In addition, my bank uses CallerID, and since
SkypeOUT doesn't transmit the correct CallerID info that makes Skype also
useless for those calls. So all this renders my tablet with OS2008 completely
useless because of this stupid bug.

6. I wasted a considerable amount of time updating my tablet and confirming
that the bug is still there in Diablo (4.2008.23-14) with available updates
(4.2008.30-2).

7. NAT is irrelevent to the issue, which exists regardless.

8. Steps to reproduce: Try making a SIP call and using DTMF key input in a
voicemail/phone banking/interactive voice response call. WTF hasn't anyone done
that yet??? It should have been done before OS2008 was released.

This is ridiculous that this issue still isn't resolved!!! It has been an issue
for almost a year!
