You're missing my point, I am currently using Nextalk 7.0 software installed on my computer and I like to keep it that way. I am a loyal user for VP-200 and Nextalk 7.0 for TTY purpose only!
Most of the time when I place a call on TTY, the user will pick up the phone but I don't see any incoming message ... just nothing. Windows firewall is disabled, Aero theme is disabled, and I even port forwarded 2590 (I think that's what I got from Nextalk website..) on Netgear WGR614; it didn't work. Sometimes it works, sometimes it doesn't. It's just annoying. I use TTY for one purpose - evidence for court purpose and other purpose as well. But with Video Phones, there are no evidence to vouch for court reason, but with TTY - there is. I can print out the conversation and bring it to court with ease.
Yep.
