I fully agree. Maybe a simple 3102 has memory limitations, but I would expect an 8-ports device (SPA8800) to alsa support T.38 with communications passing through FXO ports. Thanks to Larry's testimony, I'm aware this is not the case. > -- > _____________________________________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > New to Asterisk?
