Hi Daniel,
Thank You for the explanation - but unfortunately, our ISP still insisting to send them
back received parameter into VIA header when replying with 100.
I would like to do these changes with this ISP only. So, I tried:
if ($si=="10.1.1.100") {
send_reply("100", "Trying (Code:$cfg(line))");
xlogl("L_INFO", "Reply to ISP\n");
}
Now, the problem is how can i edit this reply before it will go outside kamailio?
I need something like "append_to_reply();" function - but to be able to modify
existing headers by using textops module. (subst_hf)
Thank You.
Hi,
In the ACK received after 200 OK the parameter 'receiving' is missing as well.
What I observed is that to some ISP Kamailio is sending back 'received' parameter,
but for some of them - is not sending. See below an invite where Kamailio is setting back
'received' parameter in via response:

In this case parameter 'received' is missing for all responses generated by
Kamailio.
Could it be that in the first INVITE - i'm receiving the 'rport' parameter in
via request, but in the second INVITE - it is not?
Thank You.

Hello,
ACK should be after 200 or a greater
response code. Is only 100 without received, or also other 1xx or
200 responses sent out by Kamailio?
Cheers,
Daniel

Hi,
version: kamailio 5.1.6 (x86_64/linux) 7d1964
Also, i'm using force_rport(); in routing configuration file, but
'received' parameter anyway is missing :(
Thank You.
