[asterisk-biz] looking for echo canc modules

[Simone Cittadini]

We have 7 TE410P , we want to upgrade to TE411P but can't find a place 
where to buy inly the dsp modules.

The only solution seems to be "give us your cards, we send them to 
digium and then back to you", but since the cards are in production is 
not quite a solution for us.

Anyone offering just the echo-canc modules ? (or willing to buy 7 TE410P ?)
