I have followed all of the directions for building on Ubuntu thus far and I could tell that the configuration step went smoothly. I have not undertaken any in-depth troubleshooting (yet) as I am not very experienced with the Freeswitch code base at the moment. It seems like I missed some minor configuration step or perhaps there's an OS issue going on here. Thanks for any help!
