Which generation of the handset are you using? They differ in their processing power and that may account for at least some of it.
For example, I had a first-generation EDGE iPhone and tried SIP clients over wifi and couldn't get anything useful out of them either. I'm yet to attempt it again with the since-upgraded 3G version but suspect the results might be better. It's hard to say, though. As for VoIP over 3G, well, AT&T's 3G + the iPhone's inherent flakyness is so bad down here in LATA 438 as a combination that I don't see that happening, even though I've seen folks pull it off with cheerful success on Sprint and T-Mobile 3G via tether. randulo wrote: > Hi, > > I've tried two SIP clients so far and both have unusable outgoing > audio quality.
