Intermittent Audio - Breakups on Android and iOS Applications

[markf100]

I have been attempting to resolve issues with an intermittent audio breakup on audio with both Android and iOS apps for some time.

There is a huge amount of information in the community available that covers all the possible issues and permutations and like many things, it is easy to blame something else in our technical world. Issues like this, described differently some times, have been commented on for several years.

I have reviewed all the fixes and analysed latency, jitter and packet loss etc across wifi, LTE etc and the problem remains. These errors are not apparent on dedicated hardware in basically the same environment and in our Covid remote work lives this has become critical to the success of the 3CX product.

With the greatest respect to 3CX engineering that delivers some amazing functionality, I implore you to do some serious research to resolve this issue.

What codecs are you using? I was using Opus but it was causing this issue, so I put G722 back and now it works much better!

HI Frederick, used all the combinations matched on phones and apps. Default is G.729 and then G.722.

The issue is related to the initial setup of the call.

Appreciate your input.

Hi Mark,

We appreciate your feedback, and would like to hear a more detailed explanation of the issue you are facing to see what we can do.

What we can't help with is obviously if the network path is interrupted, intermittent audio / breakups is not something anyone can do anything about in that specific case. Although in the ultimately worst case we do provide a reconnection mechanism when the connection is entirely severed, and if the network recovers quick enough before the call becomes stale.

Hi John

Let me put together some notes and present them in your format.

Thank you.
