FreePBX doesn’t so much manage Asterisk, but rather uses Asterisk as a tool to create a PABX and then manages that PABX. Consequently, in most cases involving FreePBX, knowledge of FreePBX is more important than knowledge of Asterisk, and that knowledge doesn’t really exist on this forum.

From your modules list, you do not seem to have any support for SIP loaded. That is most likely because the modules failed to load, in which case you should look at the full log file to see what went wrong.
