Hello,

I would also recommend using the approach with a dedicated tls module configuration file. The other way with the configuration in the kamailio.cfg is still supported I think, but don’t support configuration reload during run time.

Cheers,

Henning

Subject: [SR-Users] Re: TLS errors

Hi,

First I didn't run the 5.7 right now. 

AFAIK 1.0.2k is an additional openssl lib in Centos 7.9. Default is 1.0.1* and the RPMS (I use also Centos 7.9) from kamailio.org are build agains the 1.0.1* (5.5.x are). 

Did you test your certs for example in a httpd or so that they created right? 

Did you try it with an tls.cfg? 

Then all other modparms are obsolete except the config param. 

loadmodule "tls.so"

# ----- tls params -----

modparam("tls", "config", "/etc/kamailio/tls.cfg")

tls.cfg example:

[server:default]

method = TLSv1.2+

verify_certificate = no

require_certificate = no

private_key = /etc/pki/tls/private/YOURDOMAIN.pem      certificate = /etc/pki/tls/private/YOURDOMAIN.pem

server_name = yourdomain.example

cipher_list = HIGH:!3DES:!DES:!aDH:!AECDH:!CAMELLIA128:!CAMELLIA256:!CAMELLIA:!ADH:!SHA1

Kind Regards

my config is pretty standard so i am not sure what i am missing

using letsencrypt certs
