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:
-----------------------------------------------------------------------------------------------------------------------------------------------
INVITE sip:+123456789@X.X.X.X SIP/2.0
And this is 100 Trying generated by Kamailio:

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.
Daniel-Constantin Mierla <miconda@gmail.com>:
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.
