asterisk users - Apr 2007 - Upgrade 4 to 8 Analog Lines Question

Hello

I have an office with a T1 that provides 4 (out of 8) analog PSTN
lines thru an adtran board. I want to add 4 more analog lines.
Currently I have a Digium TDM40B. I'm wondering what the best
upgrade path is, where I define 'best' as the solution that
is most likely to work without problems (like interupt conflicts)
and work with my current echo tuning .

I see my purchase options as follows:

1) TDM40B - use with the current TDM40B
2) Sangoma Remora A20200 - use with the current TDM40B
3) Sangoma Remora A20400 - replace the current TDM40B


Any info will be greatly appreciated.

Thanks

Jim

Look at a channel bank with MGCP/TDMoE/USB interface (there are plenty
around).  We too prefer to keep fxs/fxo hardware outside of the * box.

Or a new Digium TDM880B replacing the old TDM40B for only one IRQ...

I really appreciate all the info. I think I am going to go the route  
of an 8 FXS card,
but still need to decide between Digium and Sangoma.

Are there any recommendations between:

  TDM880B - $679
  A20400D  - $906

Also, why the higher price on the Sangoma?
