[asterisk-users] Recommendation for FXO

[Doug Crompton]

I have an spa3000 and in general it is OK. I have the echo at acceptable
levels and often non-existent. The big grip is the failed rfc-2833. BUT it
might be more the fault of Asterisk - See

http://forum.voxilla.com/linksys-sipura-spa-users-group/dtmf-rfc2833-incompatibility-between-spa3000-asterisk-12306.html

and my previous (today) message to this list on spa3k

So other (external) devices may also not play well because of this
problem. Digium it seems is not real excited to do anything about this as
it is not an issue with their internal hardware and also 1.2.x is not on
the front burner with 1.4 out. 1.4 wwith it's complete rewrite of rtp code
might solve this issue. It is not clear as I have not seen an answer to my
previous question on that.

See...

http://www.voipsupply.com/index.php?cPath=96

for a listing of the external ata's. Grandstream has one, as does linksys
and others. I think they all have some issue. It is just picking the one
that has the least or the most bearable for you. Unfortunately this may
not become apparent until you get it and use it.

I too would be interested in trying another fxo/fxs as my only experience
is with Sipura.
