I was wondering which of these cards would be better for a 1-2 line SOHO. I would like room to grow as well as I am concerned with voice quality and life expectancy of the product. Any input into which one and why would be greatly appreciated. Thanks, Jon -------------- next part -------------- An HTML attachment was scrubbed...

The difference is primarily in the hardware echo canceler implementation on the a200d. The tdm400p does a fine job on pstn loops that are relatively short where the software echo canceler seems to be able to handle echo. Neither card seems to have any issues with early failures, etc, and there are no guarantees from either vendor as to future support.
The A200 is a far better card. More forgiving of Motherboards, MUCH more expandable, slightly lower cost. Only real drawback is modules are in pairs, so if you want 4 FXO, you need to buy 4. It expands to 24 ports using one PCI slot Also, if you ever are rich, hardware echo cancel is an option John Novack Jonathan Borden wrote:> > I was wondering which of these cards would be better for a 1-2 line > SOHO.

Sangoma has a better PCI interface so no interrupt or compatibility issues like you get with the Digium card. Sangoma will also upgrade the card to a version with hardware echo cancellation if you cannot solve your echo problems with the software echo cancellers. I believe you send the card in and pay the cost of the hardware echo can module. _____ From: Jonathan Borden [mailto:JBorden@Brushresearch.com] Sent: Wednesday, August 16, 2006 8:41 AM To: 'Asterisk Users Mailing List - Non-Commercial Discussion' Subject: [asterisk-users] Digium TDM400P Vs Sangoma A200 I was wondering which of these cards would be better for a 1-2 line SOHO.

I have two asterisk (trixbox) connected by IAX2 Trunk. Both of them have interfaces TE205P configured and working fine. I can places calls to PSTN on both of them. I can place calls from SIP phones connected on asterisk one, using the IAX2 Trunk, to SIP phones connected on the asterisk two. I can not place calls from SIP phones connect on asterisk one to ZAP Trunk connected on the other. Is it possible?? Please help me, I am getting crazy. Hernany Oliveira
