Actually it's digital but later converted for compatibility with
analog modems, but your point is still valid!<br>

Unfortunately, things don't get dropped as soon as we'd like them
to... Think about that abomination called T.38, when we've had email
since the 70s! :-S<br>

Yeah, I know in 2015 they should be using IP over modern
data connections (or even GPRS), but you know how it is...<br>
<br>
AFAIK, SpanDSP seems to be missing those "data modem"

Interesting.. Looks like some type
of T38 for data-modem over VoIP.
Unfortunately FS/SpanDSP don't
support this AFAIK.<br>
<br>
Also I was thinking of using a PRI
line (freetdm) to avoid VoIP issues.<br>
<br>
Thanks,<br>
