Dear....
I inserted command like this.
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.
Thank you in advance.............................
