[Linphone-users] beep sound on Galaxy S4 when making outgoing call

[Anthony Ching]

Hi,

Occasionally, the linphone app will make a beep sound when it starts to make an outgoing call (dial out).
The beep sound likes the first beep of the calibration of echo cancellation.

So far, I experienced this problem on two Galaxy S4 devices.

Any idea ?

Thanks,
Anthony
