[Asterisk-Users] Digium TDM400P vs Sangoma A200 for 2 x FXO

[Nick Chalk]

Evening all.

I'm looking at building an Asterisk system for one
of the projects of the Charity where I'm the
SysAdmin.

The project has two analogue phone lines - BT
Featureline Compact, we're in the UK - that I'd
like Asterisk to handle.

My current quandary is which FXO interface to use.
I've been looking at the Digium TDM400P and
Sangoma A200, which are similar prices for two FXO
lines. Can anyone comment on the relative merits
of those two devices? Are there any other options
in the same price range?

As we're a small Charity, price is a major
consideration. I don't think we can afford the
A200's hardware echo-canceller, for instance.

Thanks for your help.

Nick.
