Do you have other phone lines you can try the A200 with? Have you
asked Sangoma support?

Ditto on Sangoma support - they are excellent.
Do you have hardware echo cancellation on this board? (Is there a "D" at
the end of the model number?). Sangoma's hw echo cancellation is
outstanding, if you are hearing "training" then I assume you aren't
using it or the board doesn't have it.
Assuming the PC is doing other only "nominal" things, yes, this PC is
capable for what you are doing. (PC is NOT the VPN endpoint, don't have
Tomcat, SQL or a spam filtering on a mailserver running on this box,
etc.). Check that you are using IO-APIC and that everybody is getting
their own interrupts.
Do ifconfig w1g1.
w1g1 Link encap:Point-to-Point Protocol
UP POINTOPOINT RUNNING NOARP MTU:8 Metric:1
RX packets:1243390644 errors:0 dropped:0 overruns:0 frame:0

Check that errors/dropped/overruns are low if not 0. If they are not 0,
re-run ifconfig and check that the numbers don't increase (they can
have errors when the drivers first load and get synced up, but then
stabalize. Be concerned if the number is not 0 and is over 1000.
Based on your description of 2 fxo & 1 fxs board, I think you actually
have an A400 (as the A200 only accepts 2 modules total however it may
still be reported as an A200 "family" - don't know, haven't used a 400
yet).
Do wanrouter hwprobe to find out your info - note HWEC=32 means HW echo
caneller, IRQ=233 (higher than 16) means you have IO-APIC activated.

Armed with more info, Sangoma support (or us on the list) can help out
more.
