Thanks for the analysis. Do you think it would be sufficient to replace the .mkv 
with .wav in ./linphone-app/src/components/call/CallModel.cpp

void CallModel::setRecordFile (const shared_ptr<linphone::CallParams> 
&callParams) {
  callParams->setRecordFile(Utils::appStringToCoreString(
    CoreManager::getInstance()->getSettingsModel()->getSavedCallsFolder()
      .append(generateSavedFilename())
      .append(".mkv")     // <=== replace by .wav????
  ));
}

void CallModel::setRecordFile (const shared_ptr<linphone::CallParams> 
&callParams, const QString &to) {
  const QString from(
    QString::fromStdString(
      CoreManager::getInstance()->getAccountSettingsModel()-
>getUsedSipAddress()->getUsername()
    )
  );

  callParams->setRecordFile(Utils::appStringToCoreString(
    CoreManager::getInstance()->getSettingsModel()->getSavedCallsFolder()
      .append(generateSavedFilename(from, to))
      .append(".mkv")     // <=== replace by .wav????
  ));
}

and rebuild the Debian package?

Thanks
Rainer
