so that people receiving my calls would get better voice reception. A few people I called complained it was hard to hear me or that the reception was "broken up." A ViaTalk rep told me to enable DMZ for the IP address of the Linksys phone adapter (Model PAP2T) to correct these problems.
After doing so, I ran a Shields Up! test and it showed Port 80 open, the majority of ports closed and only a few indicating stealth. So, I disconnected the VOIP connection to the cable modem and re-ran the test, which now showed STEALTH for all ports.
There must be a way to improve VOIP voice quality without sacrificing computer security. Can anyone give me some advice on how to accomplish this?
