Hi, When I got the error, "No suitable codec for remote offer (PJMEDIA_SDPNEG_NOANSCODEC)", WMME-Direct was not switched on. Now it is, but there is no sound device. Is it possible to use a passthrough CODEC without any sound device?

So, for example if only PCMA is preferred: --- #define PJMEDIA_HAS_PASSTHROUGH_CODECS 1 #define PJMEDIA_HAS_PASSTHROUGH_CODEC_PCMA 1 // then disable other passthrough codec implementations #define PJMEDIA_HAS_PASSTHROUGH_CODEC_* 0 --- Repeating what Benny mentioned before, the WMME-Direct is a full sample of integration of hardware codecs (implemented as sound device), which might be usable as reference.
