Excellent adapter for the tech-savvy – helps eliminate DTMF troubles
By D. Schumann
This adapter is magnificent for those tech-savvy sufficient to configure.
Echo cancellation and jitter buffer work well.
The latest firmware allows you to increase the DTMF detection timing so that talkoff (spurious DTMF) may finelooking much be eliminated. Currently, this can’t be done using a PAP2T-NA adapter. This setting is beneath “Admin -> Voice -> Advanced -> Line1/Line2 -> DTMF Tx Strict Hold Off Time”.
If your VOIP provider supports it, then T38 faxing works somewhat well, with adaptable redundancy levels.
I’ve tried a lot of other adapters and always had trouble, this is the only one I’ll buy from now on. Anyone fascinated in a used PAP2T?

Works Great with Gizmo5/Google Voice
By W. Miller
Works well with Gizmo5 and Google Voice. Easy to configure. There are only 4 things you have to alter in the choices page, so don’t worry regarding the 200 other option fields for progressed users. The configuration under is from the Gizmo5 aid page. I only changed the lines under where I’ve added an astrisk:
SIP Settings
* Display Name (your Gizmo5 user name)
* Proxy Server (Host): proxy01.sipphone.com
Proxy Server (IP): 198.65.166.131
Registration Server: proxy01.sipphone.com
* SIP Port (UDP): 5060
STUN Server: stun01.sipphone.com
STUN Port: 3478
* User ID: 17471115555 (replacing with your 1747)
Auth ID: 17471115555 (replacing with your 1747)
* Password: (your gizmo5 password)
The Gizmo5 link for configuration is below.

Works well
By D. Conroy
This works well, and was easy to set up. I just followed the directions from the VOIP provider I chose (callcentric), changed a few settings, and that was it. Worked immediately. Haven’t had any difficulties with it.
I’m sure if you know everything regarding VOIP, you could alter all sorts of other settings (there are hundreds), and do clever stuff – but I just wanted this for a simple, cheap phone line.
