Cannot dial out, and no dial in

We have a pbx backup server that is almost an exact replica of our main pbx server. We installed everything identically. When we go to test it, it fails to dial out and incoming calls get a busy signal. We are using a redfone. It does connect to the redfone and zttool is “OK”. I’m a bit at a loss to understand why this doesn’t work. Internal calls work fine.

*NOTE: called # has been replaced by 5555555555 in the logs.

To answer my own problem.
In the CLI a “sip show spans” came back as no such command. I don’t think libpri compiled correctly the first time. A recompile makes everything golden!
