[Freeswitch-users] Tracking down calls with spoofed Caller ID

[Bipin Patel]

The way you can figure out if the person is using VoIP with a faked cli is 
normally in most countries when actual ppl call numbers, the destination 
party see cli starting with 0 followed by area code or mobile code but when 
ppl use VoIP, most carriers prefix the cli with a + by default so no idea 
if this is the case there but if I see a local cli starting with + followed 
by country code etc then I know it's a VoIP spammer call.
