5. Your problem:
I want to authenticate a customer based on the Connection Information, which is in the body of the INVITE message.
In Wireshark it is under Message Body -> Connection information (c): IN IP4 xxx.xxx.xxx.xxx

The packet in text is:

Here it is the line:
c=IN IP4 200.71.77.22

How do I use this host/IP for authentication?

Thanks

Is it this way?

$body("c=IN IP4 (.+)") = xxx\.xxx\.xxx\.xxx

Not sure if it is the correct way.

Are you sure you need to use SDP's c= line for authentication?

> $body("c=IN IP4 (.+)") = xxx\.xxx\.xxx\.xxx

It will work.

Also like this.
$sdp.audio("c") = xxx\.xxx\.xxx\.xxx
