'If you haven't properly tuned the network, you'll get choppy calls, echo, and garbled voices,' says Sheridan. According to Blanco, end users need to remind themselves that IP-based telephony is dependent on network stability. 'While IP devices have come a long way in terms of quality and reliability, they are still susceptible to network outages and virus attacks, just as your PCs are."
