DTMF tones in Skype (or how to use pin/access numbers with Skype)
I was trying to make a call to a toll free number with Skype today. The toll free number was accepted properly and I got the intial greeting but any numbers entered after that (the pin number) was not being accepted. I searched a bit and found that the reason was Skype was not recognizing the DTMF tones for the pin number.
Solution:
The solution for this is to upgrade to the latest Skype version (the current version is 2.5.0.126) which has improved support for DTMF. I upgraded my Skype installation and now I can enter pin/access numbers for toll free numbers in Skype.

latest version IV has same issue, I suspect it could be windows issue.
I am still having problems with DTMF & Skype - do you think these are related to sound card issues eg introducing distortion?
