Yea that works but the problem is the Google Voice IM field deletes itself way too frequently and reverts to a Google Voice field; see my post above. Then you have to go through all of your contacts, lick on Google Voice, and click on your GV Account in order to populate the Google Voice IM number.

The alternative is ticking the "Use GV Numbers" which will automatically add a Google Voice IM and Google Voice Call field once you input a cell phone number. It's not instantaneous as you'll need Mail for Exchange to sync your Google Voice contacts with those of your phone and then wait for TOR to poll contacts. However the problem with this is that when you get a network error it will separate GV contacts from regular ones upon polling again, giving you a duplicate of every contact. Then you have to merge all of them, which can take a while... it's better than the first method, but still...

If this network error thing can be fixed then there wouldn't be any problems, but I don't think that is happening anytime soon.
