so…which version of pjsip will work with asterisk 13? By default it doesn’t come in the menuselect, it is empty in the pjsip field if I use only the core package
The bundled version in the last 13 was 2.10[1]. You’re embarking on an unsupported setup though, so if it doesn’t work you may not find anyone further answering.
My costumers are work on Asterisk 1.8 and we need make security calls. Every aplications from my system PHP + PostgreSql are works with funcitons from Asterisk 1.8. So I can’t update my core to higher 11-13 cause lot of functions doesnt will work. Did you understand ? I think that change the core is more easy im wrong ? I need just make security call tls + certificates…
I suspect it would be cheaper to make your other components compatible with Asterisk 18 or 20 than to analyse and back port all the outstanding security fixes, given that you say your reason for upgrading is security. If I were in that market, which I am not, I would be wary of accepting without a disclaimer about security.
