I've never known adding a comma to a phone # to add a 10 second pause... at best its only ever been a 2 second pause and that was back in the days of dial-up modems. That being said, I'm not sure if it would even work on our phones (never tried it tho, so I could be wrong).

If in fact it does work on our phones, you would have to add multiple commas to get the length of pause you want, in 2 second intervals.
