asterisk users - Mar 2010 - t38 ATA

Hello,

                I need a hand in choosing a small ATA, even with one FXS port,
that should do only fax with T38.
                I've tried Grandstream (ht286 model) but the faxes go out
without ECM, even if the Fax machine has ECM enabled.

                Is there anyone that can recommend an ATA that might do the
trick?

Thanks,
Alex

The Grandstreams do T.38 quite well, and they do support ECM. It is 
probably your service provider which is blocking ECM. Many of them do.

People complain a lot about Grandstream, but its mostly their phones. 
Their ATA are amongst the better ones. Sadly, that doesn't mean an awful 
lot, as most ATAs are quite nasty.
