I know this is shocking to hear, but this is an open source project.

That means anyone can fix something. Anyone can add something. Even
you! You have all the power to affect your system.

It also means that no one is under any obligation to do it for you.

Surprising, right? I know, it's amazing to think that *YOU* have all
the responsibility and power.

We use PJSIP. We use it in a variety of settings. It works well for
us. Does that mean it works well for you? I don't know. I'm not you. I
don't have your use cases. Would I like it to work well for you? Of
course! But if you don't participate by reporting issues, testing
changes, and contributing code, there's not much I can do for you
other than to note that the line is long, and feel free to stand in it
until someone in the community gets around to what you'd like to have
done.
