Hello!
I am running into an issue where Asterisk is trying to send OPTIONS over UDP, but to the endpoints TLS port, after doing “pjsip reload”. The endpoint is configured to use TLS transport and it works as expected before the reload.
I have recreated the issue on fresh installation of Asterisk 18.4.0 with sample configuration apart from pjsip.conf.
The issue seems to happen when “pjsip reload” also outputs the following warning:
WARNING[168955]: res_pjsip/config_transport.c:739 transport_apply: Transport ‘transport-tls’ is not fully reloadable, not reloading: protocol, bind, TLS, TCP, ToS, or CoS options.
I have found 2 ways to avoid the above warning. Either remove the “#exec” line at the top of pjsip.conf, or remove “local_net”, “external_media_address” and “external_signaling_address” from transport-tls. (pjsip.conf is pasted below)
The script is needed in our production environment to load configuration-values from our database. But in this recreation of the problem the script only contains a line that prints a comment.
