My mobile phone is Sonim XP1.5 and I bought a bluetooth handsfree.
I followed the instructions to make it work. paired phone with device, connected to it.
When I called out, it worked perfectly, but when I answered a call, sound came out of my phone instead of the headset. While phone was ringing, I heard ringing sound also in headset, but when I answered, no sound ocurred.

Thank you for any help.
