Hi,
Back in Kamailio 1.5, the release notes state:
"support for TLS server_name extension (aka SNI=server name indication)"
However, I cannot find any indication of this in the current TLS docs, and trying to set tls_server_name or server_name in tls.cfg fails with "unsupported option".
Is this actually supported?
Thanks.

Hello,
starting with 3.0 we got the implementation from SER at that time (being more flexible with config and later getting asynchronous support).
A quick grep in the sources shows things related to server_name, but apparently is just for accessing them via cfg selects.
I cc-ed Jan who is author of some commits related to server name and Klaus who did the patch for old kamailio -- maybe they remember how far it got with server name implementation and if it got at least the parts from old kamailio to 3.0.
Cheers, Daniel

Indeed, currently Kamailio does not support SNI (was dropped with ser merge)

Hi Klaus,
thanks for updating on the status.
Do you remember what implied to add support for SNI?
It should be brought back if we lost it. Maybe you can adapt the old patch if it not something that complex and you have time to look at it. Otherwise, any further details about what you had to do in the past would help to add support for it again.

Adding SNI was rather easy. I used the original SNI patch for Apache and copy-pasted this patch into Kamailio. We could do this again, but this patch does not have any license details, thus I would recommend to not do it. Unfortunately I haven't found proper SNI API desription of libssl. Maybe we can find some software with SNI support and BSD license and then copy/paste the code.
regards Klaus

nginx is a possibility.

Thanks for the hint. I will have it in my mind if Klaus or some other developer has no time for it.
