The mod_com_g729 module contacts another locally running program on the server, the freeswitch_licence_server I believe it’s called. Is this running? Check your process list. You should see “freeswitch_licence_server” (note spelling) in the list. If it’s not running, start it up. If it was running previously before you applied the licenses, run: kill -HUP freeswitch_licence_server to cause the app to notice the new licenses.
