Whe iOs device paired with bluetooth speaker (not a handset!), than all sounds going through this speaker.
All sound from i2control app coming through bluetooth-speaker too.
But, when one trying to make a SIP call inside of i2control, voice (inside of call) going out from device speaker, not a bluetooth speaker.
Please, add an programmatic (or config option) to tune this feature: pass a voice through device's spekarer or attached bluetooth speaker.
