Ich habe jetzt nochmal mit 0815 Hardware getestet, AEC mit pjsua geht definitiv. Es wäre aber schön, wen das jemand bestätigen könnte.
Wal: I installed pjsip and I'm trying to understand how the echo cancellations should work. In the doorpi/sipphone/pjsualib/Config.py from your doorpi.tar.gz archive, I find the following:
Code
MediaConfig.ec_options = conf.get_int(SIPPHONE_SECTION, 'media.ec_options', 0)
MediaConfig.ec_tail_len = conf.get_int(SIPPHONE_SECTION, 'media.ec_tail_len', 1024)
If I understand the pjsip documentation well, the 0 means no echo cancellation will be done. Did you add something media.ec_options in the doorpi.ini with a value of 1? If not, I can't understand how the echo cancellation would work.
