From Asad K.: He was trying to program his cell to call the B3G to make Skype calls.
My cell phone has a setting for "Tone Length". If I change this setting to "Long" from the default value for "Short", then the dial-success rate goes up to 80% or better, as long as I also have at least a 6 second delay before entering the password#. With tone-length set to short, the success- rate is less then 10% regardless of how long a delay I put in.
