Hi team,

Can some one please let me know whether gsm card(OpenVox G400P4 QuadBand GSM Card) will work on FS, I am trying to route calls to gsm network. I saw a driver but they said its compatible only for asterisk. Do we need separate driver for this card? is there any other brand/make where I can route gsm traffic?

Thanks,

Bala

If the card uses dahdi drivers it will work with fs/freetdm

That is most likely not true. Most (if not all) gsm cards will need to send/recv AT commands, this is typically done in user space, meaning you still need some code in FreeTDM to talk to the GSM modules. Sangoma has been working in the past months in a library for call control using AT commands for GSM modules called libwat (Wireless AT)

See http://git.sangoma.com/gitweb.cgi?p=wat.git

The integration of this library into FreeTDM already started, I estimate it will be in a working state by early March. However, the initial support is only for the "Telit" GSM modules (used in Sangoma W400 GSM card), which I don't think is the same module OpenVox cards use. Getting to work the OpenVox card it is probably a matter of writing the proper AT command plugin into libwat.
