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.
