*DTX* I am not very familiar with DTX, so I may have some of these wrong:
In practice, I guess one way is to either have DTX support everywhere, or disable DTX support everywhere? At the CCC congress, we had a transcoding step between GSM and the phone operating center. Makes me wonder, the DL voice probably never saw DTX, because I doubt the conversion from "plain audio" to our GSM codec would feature DTX? I'm also thinking, the ability to do DTX maybe should also be a part of SDP codec negotiation? i.e. enable DTX only when both call legs support it? I wonder if there is a fmtp parameter for DTX, or maybe we should invent one. I haven't thought about this before, so details are welcome. *TLDR mode: enable* On another note: Mychaela, if I may ask you, please, to help us communicate, try to write less text to say the same things. It is in your interest and an important part of community netiquette to make it easy for others to respond to your messages. Aim for writing a technical "TL;DR" section instead of a text flow. It may take more time and it may hurt a bit to edit things out, but it is worth it N times over, N being the number of readers. Thanks!
