Any VOIP system will sound like hell and work poorly if the underlying
network isn't properly provisioned and configured. For best results the
VOIP system needs to either be riding on its own network or else on a VLAN
that supports 802.1P/Q priority and Quality Of Service (QOS). You also
need sufficient bandwidth. One single uncompressed VOIP call will actually
take as much as 80kbps of bandwidth. True, you can compress with G.729 but
then the voice quality suffers.
