I have done an extensive hoeing out of the VoIP Resource Guide, if you thought it was getting a bit long in the tooth, there are new items and I’ve deleted a lot of the old stuff. But, to cut the chase, here are some Stuff That Works:

• Trixbox 2.2 – implementation of Asterisk
  
• Polycom SoundPoint IP320/330 Phone
• IDEFisk Softphone for IAX2.
• Voicepulse for SIP and IAX termination to the regular telephone network.

The above are components that I’ve been using recently. Just today I ordered another Polycom phone, and a Sangoma A200 FXO card to replace my Digium X100p card. The difference between the Polycom phone and the Grandstream B100 phones in sound quality is noticable, and the general fit and finish of the Polycom phones is outstanding. Of course they cost twice of what the Grandstream phones had cost.

Other things highly thought of:
At the Boston Trixbox seminar, people spoke highly of Aastra phones, and Rhino interface cards. M0n0wall, the open source firewall was also recommended.

Unsolved Problems:
I was really happy with Gizmo for awhile, but have never been able to get it to register with my Trixbox server. I fiddled, but always given up.

And, still looking for a QoS solution for my home router, so that when I’m on the phone, and am casually surfing the web, it doesn’t destroy the conversation mid-word.
