Yes audio inside of a data connection over a data connection is how it should be done. /me bashes head on desk, this seems futile... There is this thin called the INTERNET, its already a data network, we should probably start using it! :P On Fri, Feb 20, 2015 at 11:37 AM, François <fdelawarde@wirelessmundi.com> wrote:
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.
Yeah, I know in 2015 they should be using IP over modern data connections (or even GPRS), but you know how it is...
AFAIK, SpanDSP seems to be missing those "data modem" stuff (V32 at 9600 and V92 at 56k)...

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.

You want v.150.1, GOOD LUCK!

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

Self answer: Apparently SpanDSP does not support V32 nor V90/V92.
Also I can't seem to find any other solution. The objective was to fetch data from remote GSM sensors using simple protocols over V32 and similar...

Hi all,
As seen in the HylaFax wiki entry, mod_spandsp can be used as a soft-modem. https://wiki.freeswitch.org/wiki/HylaFax
Can it also be used as a data modem (not just fax modem) with V32, V92 or similar protocols?
If not, does anyone know of any data-modem software that could work along with FreeSWITCH?
Thanks, François.
