Hi Bogdan, It would be nice to get rid of these AVPs, and select client domain by destination IP, but the problem that I have only 1 destination gw IP for all customers domains. I have cloud platform, which I’d like to connect from OpenSIPS. And I have many customers with their domains.
So the only way to choose client tls domain is AVP. And why not to allow manipulate AVPs in local route? I modified modules/tm/uac.c little bit, and now I can select TLS client domain with AVP from local_route. https://github.com/OpenSIPS/opensips/issues/1642 But I’m not sure about the code. And sorry, that I marked it as bug, I thought that it is normal to work with AVP variables from local_route. I have another issue, that OpenSIPS reuses TLS connections the same way as regular TCP connections, but it should not. For reusing TCP connection we check, if connection with the same dst IP:PORT exists. But for TLS it is not enough. We additionally should check, what certificate uses this connection (or what domain it is related). If on server side we have SNI, why not to have more control for client TLS side? ----- Alexey Vasilyev alexei.vasil...@gmail.com > 25 Mar 2019, в 18:37, Bogdan-Andrei Iancu <bog...@opensips.org> написал(а): > > Hi Alexey, > > Well, the AVPs (as variables) are not visible for the TLS send operation.
