[mmena at iusacell.com.mx]

Scenario: It's intended to redirect an initial call -originated at 
10.208.59.131-, through an second INVITE from 196.18.4.105 to 
10.208.59.131

Following is the header of first INVITE message (from 10.208.59.131 to 
196.18.4.105)

Is it correct the "From:" header?
IP adresses at "From" and "To" are the same.
