Hi all! I compiled the source code of the openbts-umts project as well as the subscriberRegistry subscriber registration module. As equipment I use usrp B200. I have registered my sim card via /nmcli.py tool. I’m running openbts-umts and using my phone to search for a 3g network I’ve created. The phone sees the created network. However, I cannot connect to this network. The phone says that the selected network is not available. Maybe I misconfigured the configs? At startup I get the following warnings:

When I try to connect to the network, I get the following output:

Please tell me, maybe someone already has a working configuration or clear instructions on how to set it up in order to connect phones and make test calls?
