Hello,<br>
<br>
I'm having an issue where kamailio is not sending the failure reply
as I would expect when receiving calls from a certain provider.
Kamailio sends the 403 response on calls from other providers. The
big difference I see is that the "problem" provider is using compact
headers. I am trying to force the 403 response to be sent for
testing purposes but I just can't get it to reply to this one
provider. <br>
<br>
I've included traces and configuration excerpts below. Any help is
much appreciated!<br>
