Hello there, I would appreciate if there would be a step by step guide to how to configure the pbx for encrypted calls. the pdf manual guide does not explain the installation and configuration of the SSL certificate.
Second. I am hoping we can get some best practices as well as brand-specific documentation, especially Grandstream and Yealink. I have had mixed success with OpenVPN on Grandstream phones, in line with others’ complaints on the GS forums.
