Re: [Kamailio-Users] add_path_received and OBP problems

The request sent out by the LB still has the Route header. This indicates that either: - the load balancer does not detect the domain/IP in the Route

as an internal one (alias=....) - the loose_route function is not called in the LB.

Proxy is adding a route-header according to the path-value in the mysql. That seems also correct. Now to my problem: > > The loadbalancer is sending out the INVITE to the private-ip, not

the public-nat-ip of the UAC. It seems that the received-parameter in the Route-header is somehow ignored. I am using the use_received parameter in the loadbalancer, but it does not work. loadbalancer) and the loadbalancer config, since I think there is the problem. > > Thanks, > > Florian > > > Here is the SIP-trace of the INVITE: > > 09:49:07.785294 IP [Proxy+Registrar].5060 > [Loadbalancer].5060:
