Hi users, I use pjsip since 2015 with C-Media-USB-Stick on Raspberry PI 2 (Jessie). It worked great. At the new Raspbian Stretch I can't use PJSIP, because the audio quality is terribly. I install pjsip with the following commands: 1. sudo ./configure --disable-sdl --disable-ffmpeg --disable-openh264 --disable-libwebrtc (without --disable-libwebrtc the make-command provides an error). 2. make + clean + install Audio-Tests: 1. aplay "wavefile" - works great 2. pjsua - test: cc 0 0 works with --clock-rate=8000 better than higher clock-rate, but not good enough. I try codecs, also PCMU, PCMA. Other functions like call, answer ... work great. What can I do that the audio also works like under Raspbian Jessie? Excuse my expression my english is not so good.
