[asterisk-users] Sangoma or digium ?

[Leon de Rooij]

Hi all,

We need to get better echo cancellation on an Asterisk gateway.

Currently it has two TE410P (1st gen) cards. So would it be possible to
just buy two VPM450M cards ? Or do we need to buy two new TE412P cards ?
In that case a Sangoma A108d card would be nice as well ?

What configuration gives the best audio quality ?

Thanks,
