[OpenSIPS-Users] Loadbalancer for Registrations and calls

Wed Nov 2 18:00:20 UTC 2022

I am not seeing an option, but Is it possible to hash on the Contact
Header?

Right now I have it hashing on From Header and I know that the From on the
Register and the From on the INVITE match except for the tag. I added the
"u" flag and it is still not working.  What it is doing is looking at the
DNS record of the R-URI domain and routing on that.

 $ru = (ds_select_dst(1, 1, "u", "default", 1));

How do I get it to not use the domain in the R-URI to route on.

Thank you.

Kevin
