running mod_gsmopen on a separate system
I'd like to use FreeSWITCH as my private bridge between SIP and GSM. However, I consider USB modems to be a security threat, since they frequently have their own storage (can work as pendrives), have a black-box baseband and are hardly ever patched. For that reason, I'd like to connect my USB modem to a separate machine (maybe an OpenWRT router) and connect that machine to my main FreeSWITCH machine over Ethernet. How would I set that up? Can mod_gsmopen be run alone, or would I have to install a separate instance of FreeSWITCH on that second machine? Thanks! PS. I'm still trying to wrap my head around FreeSWITCH, so please be forgiving. :)
Thinking "install a separate instance of FreeSWITCH on that second machine" is preferred. On Wed, May 13, 2015 at 1:58 PM, Mietek Sześniak < mietekszczesniak2503@gmail.com> wrote:

Yeah, that is what we do basically. Get our modems hooked to a raspberry pi with freeswitch and route the calls&sms via sip to the endpoints. Giving it a little thought though gave me that : http://usbip.sourceforge.net/ It's a simple encapsulation of usb messaging over IP which is transferred to a kernel module acting as a virtual host controller. Haven't tested it, but be sure to post some feedback if you give it a spin. On Wed, May 13, 2015 at 2:32 PM, Giovanni Maruzzelli <gmaruzz@gmail.com> wrote:

Passing USB messages via USBIP equal inserting dongle to FS host. It is not solves security questions. Sergey On Wed, May 13, 2015 at 4:02 PM, Daniel Ivanov <sertys@gmail.com> wrote:

Yeah, you're correct but i can believe there can be some ACL or whitelisting implemented on kernel module level. Keep in mind the USB modem comm is just a bunch of serial consoles and you mitigate the problem of DMA(direct memory access) if you just choose to relay that class.
