VIA SIP header

SIP VIA header tells the receiving device where it should respond:
INVITE sip:45555@10.108.1.12:5060 SIP/2.0
Via: SIP/2.0/TCP 10.108.2.41:5060;branch=z9hG4bK100EDA11
Respond to 10.108.2.41 at port 5060
Tip: You can test the remote port with any telnet client i.e. “telnet 10.108.1.120 5060”
