Solved Certain Extensions Making Calls by Themselves to Other Extensions

[JohnathanP]

I have 2 extensions on a clients instance that I have seen make random calls to other extensions. They never make random calls to outbound numbers either. I have already changed the passwords for all extensions, no WAN registration is available. So why do I see these extensions making random calls, both users use the new Desktop App or Web Extension.

Hi @JohnathanP,

We've had a couple of reports of this but it seems to never happen again. I've set instructions in this thread:

Can you also enable verbose logging on your PBX and once the call completes, generate Support Info and attach it to me in a PM? I'll need the time of the call as well as who was called and from whom.

So I'll need the logs request above and the generated support info. When the calls happen, is it specifically in the Desktop App or the Web Client? Does it happen with both? Is it reproducible?

Can you let us also know which headset you have on the desktop app that is making these calls automatically, please?

 

[JohnathanP]

They are using Logitech H390 headsets. I haven't seen the calls happen in a couple days, I will let you know if I get any more.

Hi @JohnathanP ,

I will send you a PM soon regarding this issue.

We have found a way to replicate this in-house and we believe to have found the root cause.
You can remove any debugging you may have enabled and we plan on providing a fix for this along with V18 U2.
