New subject: Determining if request is from a local domain

13 Jul 2016


      Hi all,
Solved!
As is often the case, after working all morning on the problem, after posting I discovered my error.  I noticed that I hadn't included in my post the "alias=" command.  It was indeed in my script but I had used aws-rcsstg.voip.systems instead of aws-rcsstg.vvoip.systems !
I don't know how many times I have stared at that but I guess you often see what you want to see......
Apologies for wasting your time.
Kind regards
Shane

Subject: Determining if request is from a local domain
Hi all,
From previous posts my understanding is that RURI's are matched against
reverse DNS lookup of listen addresses and aliases set via the "alias="
parameter in the config file (assuming the domain module isn't being used).
However I am having difficulty in getting this to work. From looking at the
code and the log file, it appears to me as if the alias isn't making it into the list
of hosts that is checked against for some reason.
Kamailio proxy is behind a loadbalancer (Kamailio dispatcher) and proxy is
trying to relay the request because it doesn't recognise it as a local domain.
Any thoughts on where my error is would be appreciated.
Relevant CFG file section - note that
RCS_LB_PUBLIC_IP:RCS_LB_PUBLIC_PORT  is 52.64.xxx.221 :5061
