Using pauses in stored contact numbers for dialing.

Question

Apple or anyone,
I am trying to add a pause after a phone number. Specifically, I want to add the PIN for my calling card after the number. Before posting this call for help, I read through many other Apple Discussions on the topic as well as other internet sites. I understand that the Pause (or comma) feature can be found on the dialer. I have tried manually entering in the comma, using the formal "Pause", varying the number of pauses, and I've tried to access the number through the contact app and the phone app. I've even shut the thing down to see if that worked. All with the same result.
My phone will dial the first number up until the first pause, then absolutely nothing else. No pause, no long dial tones like some other posts talk about, nothing. For all intensive purposes, my pause feature is completely inop.
Apple, or anyone else, do you have a suggestion? I'm using a brand new iPhone 3G with 2.2.1 loaded. I also live in Japan.
Cheers,
Hector

I don't know about what you are referring to when you refer to a "pause/comma comma feature can be found on the dialer". I haven't found one.
The only way I found to successfully get commas/pauses in a phone number is to put the number in my address book and then sync that to the iPhone. It works great. I believe that each comma is about a 2 second pause (don't quote me on that part).
