1. How can I setup 3G usb? I connect and nothing happens…

I haven't played with the intercom yet. I suppose a Arm build of alsamixer console audio mixer might help tackle the audio levels. You might want to check https://github.com/matiaspl/LinkPi-ENCx/issues/5, there are some clues for how to make your 3G usb modem work.

Hi Matias! 4G USB is solved! thank you very much.. This solve my problem: KERNEL=="usb*"

SUBSYSTEM=="net", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14db", KERNEL=="usb*", RUN+="/etc/udev/usbUp.sh ....

On the other hand, I dont know how install alsa-utils or similar to up volumen in Intercom... Could you help me..

Thank you very much!

You need a statically compiled amixer from alsa-utils or https://github.com/tinyalsa/tinyalsa to do volume control. I haven't found any source of these binaries myself (yet).
