My guess is you need more upload. 1mb is really 120~kb/s split 4 ways is only 30kb/s which may not be enough for your VoIP quality setting. *that's assuming nothing else is running and your getting full speed. /edit I could be wrong I don't use VoIP :/ »techtips.salon.com/much-bandwidt···127.html "Depending on the protocol used, each concurrent call requires a bandwidth of between 30Kbps to 80Kbps." " A low-end 2Mbps download and 512Kbps upload broadband connection should be enough for two or three concurrent calls"

You are mixing up kilobits (kb) with kilobytes (kB). 1 megabit is 1024 kilobits, or 128 kilobytes. A VOIP call at most should be 64 kilobits or 8 kilobytes. 1 meg should theoretically support 16 simultaneous 64kb phone calls, but in reality wouldn't leave any headroom. Either way, a few simultaneous calls should be fine.
