Yes. This card supports it.

This is not quite correct. Your card actually has 4 controllers, so you
need to create 4 sections (contr1, contr2, ...) with devices=2 each.
!Oh, you use M-Adapter. Then your 4 channels should be working!

Also, to make use of the DSPs, don't set softdtmf/relaxdtmf. And
since you are using a newer driver, use echocancel=yes and leave
echocancelold=off, otherwise your echo-canceler will not work.

Okay, both should be bridged. So somehow it is not activated.
 
So please provide a log with
  set verbose 5
  capi debug

It is a capi.conf (chan-capi) parameter and is part of the example provided
by chan-capi package.
So far the DIVA Server cards are the only cards which can do RTP.
But it is okay to leave it off.
