How are you attempting to do your voice call? Instead of using the voice call, which for some reason does a horrible job use the search and simply say "call John mobile" or whatever.
I've had no problems with handcent so I can't help you there. I would suggest that you not use a title like the one you chose, it's not helpful when doing a search.
Ditto on the last comment. Post anything you want, but IMNSHO, trying to create meta-topic megathreads a la HoFo when we aren't moderated by militia only reduces readability of the site. Zoom out to the forum level, and for the most part you see a problem and solution discussion segmented by topic. I don't read a thread once it gets over 80 posts, it's guaranteed to have low signal to noise ratio. Just one irrelevant monkey's two cents...
