[Freeswitch-users] Determine if a number is valid/working

[Ken Rice]

Theres only a few ways to know for sure, a) dial the number see if you get a
reject or not lol b) lidb lookup (not always possible) c) look in lerg to
see if the NPA-NXX is even valid in the first place, you can also try LNP
(and maybe CNAM) lookups to see if you get a valid result there, it is
possible to get a CNAM on a disco¹d number...
