RE: [Serusers] SIP/2.0 483 Too Many Hops

Here, try this script.

What I want is that when I loaded test.cfg file, what I check SIP messages using sipp client mode I want 200 OK. But, as you see, I received "SIP/2.0 483 Too Many Hops" error message. So I was advanced about this. - alias="sam.cse"//SIP_ DOMAIN alias="server.sam.cse"//my_computer.SIP_DOMAIN alias="192.168.178.194"//my_ip - add my hostname in /etc/host - change to : if (!mf_process_maxfwd_header("100") but, I couldn't solve this problem. I would really appreciate for giving some advise.
