Hey @sherif.abdel-moemen,

Thanks for using the dev forum!

Can you elaborate on what you mean by this?

Are you receiving errors? Is the audio not connecting? Is the audio connected and unmuted, but there is no sound?

Thanks!
Michael

Hi Michael,
The audio is not connecting. the video is connecting though.
Thanks,
Sherif

Hey @sherif.abdel-moemen,

What error is returned when you call unMuteAudio?

Thanks!
Michael

Hey Michael,
I am getting SDKERR_WRONG_USEAGE when calling unMuteAudio.
Thanks,
Sherif

Hey @sherif.abdel-moemen,

Gotcha, try calling JoinVoip after you have entered the meeting.

Thanks!
Michael

That fixed it. So for completeness, I am assuming I have to call LeaveVoip both when I am ending the call or leaving the call. Is that assumption correct?

Hey @sherif.abdel-moemen,

If you leave the meeting or end the meeting, the audio should automatically disconnect. There is no harm in calling LeaveVoip when you are leaving the meeting, but it should not be necessary.

Thanks!
Michael
