Impresive. What I was planning to build myself with spare parts, already done with a USB dongle.
That will be a godsent if you have a couple of warehouses in diferent locations, or just several locations anywhere.
Now, does anyone have found a device that goes directly, like in one box aproach from VOIP H323 to GSM????
I found several boxes that are suposted to do SIP to GSM cell phone in one box, but have not found anyway to make if from GSM cell phone to H323 on one box.
