I've seen some posts about this issue, but yet to find a resolution.

Like many, I call a number to access my work voice mail remotely. Upon picking up, the system prompts me to dial my extension (e.g. 1234), then #, then my password (four digit number) then # again.

With my old Blackberry Pearl, it was simple. I programmed the phone with(999) 999-9999p1234#1234# and iDrive dialed it perfectly everytime.

I now have an iPhone 3GS, and programmed the number using it's standard of a "," comma, for a pause. So the number looks like this:
(999) 999-9999,1234#1234#

The problem is, the iDrive systems appears unable to recognize the "," and as a result, doesn't display anything after the 10 digit number, and of course, doens't dial the extension or password.

Is there a fix for this? Or any suggestions about what I may be doing wrong?
