Steve,

I was under the impression that spandsp does implement a V.29 (9.6K) with V.42bis (compression and error control).

But I might be wrong here.

Are you under the impression there are duplex data modems in spandsp? If
so, its a false impression. There is a V.22bis modem, but it is not
exposed in the AT interface provided for the FAX modems.
