I've noticed that the voice quality of my Vonage line has *improved*
lately. The line seems far more resistant to echo in the past few
months.

When I first got my Vonage line, I had many dropouts. I have a Cisco
ATA, and I use a UNIX system as my home firewall/router. I was able
to improve the reliability and call quality quite a nbit by configuring
my firewall to give priority to the Vonage packets and to TCP ACK
packets in general. Less geeky users with consumer-grade home routers
may not have the ability to do this.
