[Freeswitch-users] How to receive call using gsmopen

[Anurag Rana]

Hi All,

I have micromax usb dongle with a gsm sim in it attached to my system.
mod_gsmopen has been compiled and has been loaded. Freeswitch is running.

*This is the output of lsusb command -*

I searched internet for "how to receive a call using FS" or "How to make an
inbound call using gsmopen"​
​ but could not find detailed stepwise explanation.


Can someone please tell me what I need to do next so that when I call the
sim number in dongle, call is received by FS and actions are performed
based on dialplan.

OR

direct me to some link which explains this. (apart from this
https://freeswitch.org/confluence/display/FREESWITCH/mod_gsmopen)​


​Thanks​
