I didnt find anythng on google so posting here:
sipp 2.01 - windows
Im running simple scenario
INVITE -->
100 <--- OPTIONALL
180 <--- OPTIONAL
OK <-----
ACK --->
pause 10s
BYE --->
OK <----
Before that UAS and UAC users are registered at the proxy
Two things happen now:
1. Proxy receives BYE without Max-Forwards - this can be easly hacked on
proxy, but its a hack
BYE sip:[EMAIL PROTECTED]:5060 SIP/2.0
Via: SIP/2.0/UDP 127.0.0.1:5560;branch=z9hG4bK-2284-6000--1
From: "sipp" <sip:[EMAIL PROTECTED]:5560>;tag=6000
To: "sut" <sip:[EMAIL PROTECTED]:5060>;tag=6000
Call-ID: [EMAIL PROTECTED]
CSeq: 2 BYE
Contact: <sip:127.0.0.1:5560;transport=UDP>
Content-Length: 0
(this is content of message read directly from socket)
2. Proxy receives strange requests, which can loop around proxy unless it
drops them.
