Hi there, can you please execute "audit" on OpenBTS CLI and post it here (it is better than sharing the all config). Also describe your setup (PC, SDR, phone), distance from the phone to SDR, then I will look into "power" and "rxgain" parameters..., also ... before initializing OpenBTS, have you executed any command related with "iptables"?
Regards
from openbts.

I'm using a think-pad based on i7, Ubuntu 16.04, USRP B200 and OpenBTS
the MS is inside the faraday cage placed close to the USRP B200.
Power:
OpenBTS> power
current downlink power 0 dB wrt full scale
RxGain:
GSM.Radio.RxGain "10" ("47")
Before initializing OpenBTS, have you executed any command related with "iptables":
sudo iptables-restore < /etc/OpenBTS/iptables.rules
I'm still stuck on this issue.
Pls, help I don't understand what I'm missing.
Regards.

Fixed the issue.
I had no Ethernet connectivity changed the interface to WiFi in iptables.
One of the devices i was using using had a carrier's SIM which was programmed for DCS 1800 so had to tweak OpenBTS for the same config.
