Now I need to decide between the Sangoma A20202 and the Digium
TDM2411. I'm leaning heavily toward the Sangoma card for the
following reasons:
- It doesn't require a 12V power connector for the operation of FXS
modules.
It certainly does!
- It is compatible with 5v and 3.3v PCI buses.
- It shares PCI interrupts properly.
- It maintains a single synchronous PCI interface for all FXO/FXS
ports (additional daughterboards are added to a backplane bus connector)
- It has a better form factor.
- It is less expensive.
If the need for a connector isn't a killer, the Sangoma A200 is a much
better choice.
They have a 5 year warranty
The will work with any modern motherboard
They have good/great support. If it doesn't work, they will NOT tell you
to try another motherboard
If by chance you need pulse dial, they have a different driver that may
or may not be on the website.
Ask David in support for that.
If you have boards other than the A200, keep in mind that it takes up 24
channels, used or not, so if, lets say, you have an X100 in addition (
don't know why you would ) and its driver is loaded second, it will be
channel 25
Sangoma is the wise choice, in my opinion.

These are rather compelling reasons, but I'd still like some feedback
from the list prior to making a purchase.
Both cards offer hardware echo cancellation for an additional cost.
Do the benefits of hardware EC justify the expense in this scenario?
Thank you,
