Mazilo, well, as anyone said, you can't know that for sure. Here, in France, and I think this may be applicable in most western countries, the end user of a telephony service will always receive only one CLI. If the call comes from an analog line on the PSTN, the CLI is provided by the telco. If the call comes from an ISDN line on the PSTN, the CLI is the one sent by the caller's PBX. So for calls coming from ISDN, the telco will always add another CLI, the real CLI of the customer. We call it NDI in France (meaning Installation Number). For SIP, you can guess what applies: no rules... So basically, if you are a end user (not a telco), you will receive a CLI which can be fake. If you are a telco and are interconnected in SIP or SS7 in the right way, you may (meaning "you are allowed to") receive the 2 CLIs for calls coming from ISDN. For SIP calls, the issue is still there anyway: the reliability of the CLI depends on the seriousness of the ITSPs out there.

Today, after my phone rang with a CID of (443)366-9222, I took a look at /var/log/freeswitch/freeswitch.log file on my Seagate DockStar (excerpted below). What caught my attention is the last line which shows two numbers, namely 4433669222 and 4016488312. The question I have is if 4433669222 is a spoofed number?
