[Asterisk-Users] chan_capi: advice needed on isdn card

[Michiel Betel]

Note that the CAPI driver for the Fritz! only supports a single card. So if
you want to expand your asterisk in future you can't just add a 2nd cheap
card...

Morning Chris,

1. it's not predictable if you will get echo with the passive AVMs (and
probably also not predictable with the actives).

2. yes.

3. the passive Eicons (those without the word "server" in the name) have no
echo cancelation and not even a capi driver (so you're stuck with i4l). but
not all active Eicons support echo cancelation!
Bicster: can you shed some light on this? :-)

regards
kapejod
