[Freeswitch-dev] Best way to test DID is hitting Freeswitch

I have thousands of DID's and wondering what is the best method to run tests to see if these numbers are hitting our Freeswitch server. We have problems with our carrier assigning our numbers to other companies and need to preemptively know if the number is not pointing to us anymore before our clients find out. Currently, I run a command to originate a call for each DID which updates a database entry to see if that number went through are server. I am looking for a more efficient way to test all these numbers. Thanks. - Jim
