Solved Call Quality issue during Conference

[techdummy]

Hi,

We have an issue with our Conference system.
The issue is that the call quality is very poor, crackly, lots of distortion and we are unable to hear the client properly. They are unable to hear us too. We tried changing the devices but the issue is still there.

Any ideas about what might be the possible causes? And how to go about troubleshooting this issue?

Thanks

Hello @techdummy

What phones are you using?Are they using the default templates? Have you ran the firewall checker with no errors??

Thank you

Hello @IoannisM_3CX

We are running 3CX client for windows and have configured it to use Jabra Speak 510 for conference.
Firewall checker didnt show any errors.

Hi,

When you use only the 3CX client with no speakers or extra devices, does the issue occurs??

Hi Techdummy.

this sounds like you either have a Problem with the Jabra or that your Internet link is too slow to accomodate for all the calls which are used during the conference.

Are these Voice conference calls or web conference calls? (I ask because this determines where the Audio mixing is done - in your 3CX or on the conf Servers of 3CX).

Also you should consider/answer the question of IoannisM as this is relevant to distinguish between error of the Jabra oder the Internet link.

With Kind regards,

John

Thank you for the replies @IoannisM_3CX and @John Ranger
Since I'm administering everything from remote location. It takes a little bit time if I want to check the hardware being used.
I had a check on it with our VMware admin and a staff from the remote location, and it seems like the issue wasnt related to 3cx. Jabra is faulty but the main issue is that they haven't selected the right audio device while configuring 3CX client.

These are video conferencing calls, so the audio was being picked by the webcam it seems.
