Tip: Selecting a different audio device for ringtone
The perfect audio setup (or at least a very effective one) is using a USB handset for playback and microphone, and outputing ringtones on the internal speakers.
To do that in SFLphone, go to Edit > Preferences, select the audio tab on the right column and use the following settings:
- Sound Manager: ALSA
- ALSA plugin: dmix/dsnoop
- Output: USB headset
- Input: USB headset
- Ringtone: Internal device
