I'm looking to handle 3 PSTN lines with my Asterisk server. I have a
Digium TDM22B and Sipura 3000. The Sipura works great, but the TDM22B
seems to have terrible problems with my board---virtually all
peripherals need to be disabled in BIOS, and then there is terrible
noise, terrible silence and virtually no ability to use DTMF in IVRs.
I really wish the TDM22B worked, because I much prefer storing all my
configurations on one device, and not needing separate peer accounts
for each PSTN line. However, I don't have the skills or spare
hardware to debug this quickly, and I'm really wanting to get on with
the task of developing some AGI apps.
I see several 4 port FXO Analog/SIP gateways on voipsupply.com:

I know it would be cheaper to buy two more Sipuras, but it might be
worth the extra $$ to cut down on the power adapters and have a
centralized point of administration, especially if it didn't involve
dozens of browser mouse clicks to 3 separate HTTP servers.
Reliability is the primary criterium, though.
Can anybody give any recommendations? And are these digium problems
unusual?
We now have three installs of the Sangoma A200 (with echo can) and love
them. They sound quality is very good and, so far, they have totally
eliminated echo.
