You're welcome!

In Asterisk is allows you to set a path to the openssl files. Typically
used if your install of openssl is in a non-default alternative location.
For example:


I'm not really sure how Asterisk accepts the parameter without a file path
specified. My guess is it either uses the default path, or potentially sets
some flag meaning ssl is required.

See above. The flag is still needed in Asterisk. However, the setting
appears to propagate in some way into the bundled pjproject configuration.
This is in some way affecting the build of pjproject, then subsequently
causing res_pjsip in Asterisk to not load at runtime. Further investigation
is required as to why though.
