1. Who sends no `telephone-event/8000`, Asterisk? 2. In which scenario, Asterisk as caller or Asterisk as callee? 3. If it is not Asterisk, does the session include further SD audio...

I am asking _several_ questions and get _one_ answer. I cannot work on this issue, if my questions are not answered step by step. I am not asking questions for...

Yes, when you start the call within Asterisk, the current code does not send an fmtp-line because the module uses the defaults of [RFC 4867](https://tools.ietf.org/html/rfc4867#section-8.1) and all attributes are optional....

Implementation takes around two hours. However for this, I do not see any resources (available time-slot) till Christmas. Beside that, I have no idea how to test that additional code,...

Thank you for the offer. It is always good to have a second testing environment. However, I am looking more for at least one test case: When does who change...

No. I inherited that code part from @seanbright and he inherited that part from @meetecho. Personally, I never used it, so I am not even sure that part works at...

The Asterisk team seems to have different defaults in their `opus.h`. I know, you prefer 4 from your practical experience. Anyway, is it possible to align those values somehow –...
