When I have ext 1 dial ext 2, on the caller's phone, instead of saying "To: 2", it says "From: 2".

I'm using kamailio version 4.0.4.  I'm just new to everything kamailio and VoIP so I apologize in advance for any remedial questions. 

So far, I've done a SIP trace to and checked all packets line by line to see if I could spot where the To address was erroneously changed to FROM.  In particular, I was checking the call-info fields for caller id data or any other data what would appear on the LED of the phone. 

Now I'm wondering, who's job (aka which module) is it to set the caller id information for both phones? 

I'm thinking of digging inside the code for the right module just to see if I can follow what's going on 

In addition to answering the question above, if you have any suggestions on what else I can check or try, I'd appreciate it. 

Thanks List!
