[Freeswitch-users] USB GSM Dongle with FreeSwitch for voice calls

[rumodigital]

Hi Giovanni,

I'm in the testing phase in a Mini ITX board (Atom D2550 + debian 7.6 32b)
and DUB-H7 USB HUB​. I use 4 devices simultaneously (4x 500ma = 2A) and yet
everything perfect!

7-Port USB 2.0 Hub (500ma on all seven front ports, but 3A in total)

Do you recommend some other HUB?

Doug
