When you hear echo, the problem usually originates at the far end.
We recommend that you ask the other party to:
(1) Set his/her speakers’ volume to a comfortable level (not too high). Also, they should try to keep their speakers away from the microphone.
(2) The other party should either install SoliCall as well (since SoliCall has built-in algorithms that reduce echo) or use headsets.

(3) Activate the option of “Incoming Echo Cancellation” in SoliCall Pro.
