Solved 3CX APP Request Failed when Making and Receiving calls.

[Armand Brits]

Hi.

I trust you are well.

Could someone please help?

My client's 3CX app stopped working 2 weeks back and I can not get it to work again.

• Phone Model: Hisense U40 Lite
• Android Version: Andriod 8.1.0
• App Version: [16.0.1.X]
• 3CX PBX Version: 3CX V18 hosted on AWS
• Network Connection: Wifi- Fibre IPv4

What I've tried.
- Disabling Telecom API
- Disabling Echo cancellation.
- Changing Codec to Android chooses.
- Turned Off Battery optimisation.
- Checked app permissions.
- Reprovision App.
- Uninstall the app and re-install.
- Instaling App Beta version.
- Upgrading the PBX to Version 18, and reprovisioning the app again.


The Ext does work on a Samsung Note 10+ and other users connected to the same network do not have issues.

The app provisioning reflects in the 3CX server's logs but can not see any of the call attempts.

Can anyone tell me what else I can do?

Highly appreciated.

Hi @Armand Brits could you give a try to 3CX Android BETA App and let us know if it sorts it out

Hi Gian.

I've already tried the BETA app. Unfortunately no luck.

With the Beta app, I've also tried changing the Codec settings, Telecom API, Echo Cancelation ETC.

Kind Regards.

@Armand Brits actions already taken. Thank you.

@Armand Brits could you please increase the log buffer size in the android developer options and send logs again.

 

[Armand Brits]

Hi Giannosl

Thank you. I've done this.

I've uploaded the new logs onto the same link.

The device only allows for a max buffer size of 1M

Kind Regards.
