I don't know about v.150, but lots of devices (telecare and other
sh..ty IoT stuff) use V32 over crappy GSM modems. Right now can't
talk to those without a "real" modem.<br>
<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" stuff (V32 at
9600 and V92 at 56k)...<span class="HOEnZb"><font color="#888888"><br>

One of the reasons that has kept any work ever happening on this
is we can't seem to find a single device that actually claims to
support v.150. Spandsp already has quite a bit of the modem code
for 9600 and 14400 but its not exposed to a data modem interface.

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>
François.

Apparently SpanDSP does not support
V32 nor V90/V92.<br>

Also I can't seem to find any other
solution. The objective was to fetch<br>
data from remote GSM sensors using
simple protocols over V32 and
similar...<br>
