I am debugging a new/initial Freeswitch configuration.

I believe that I have successfully registered with my VoIP provider — “State=REGED”.

I am able to dial from one extension (x1000) to a different extension (x1001), but after answering, there is NO AUDIO at either end of the call.  Problem #1.

When I test call to extension x9196, for example, I get an immediate hang-up and SIP response of “SIP/2.0 480 Temporarily Unavailable”.  Problem #2.  Do I have to do anything to enable calling to x9196?

And when I attempt to call an external phone number via my VoIP provider, I get the same immediate hang-up and SIP response.  Problem #3.

I am getting this critical error on startup.  Problem #4.

**/usr/local/freeswitch/mod/mod_v8.so: cannot open shared object file: No such file or directory**

Any suggestions as to what configuration might be wrong?  Or how I can get additional debug information?
