3cx standart annual 16.0.9
problem with any android smartphone even within same subnet. this means its not routers problem. router is mikrotik. 3cx on windows 10 with last updates.

we tried with many smartphones . same problem. no matter wifi, 3g or lte. battery full or less

i can send you any extension & give remote connection if you wish

 

[NickD_3CX]

I'd also like if possible if you could send us the version of the Android App your are using.
Also, when you say it happens on WiFi, is the Wifi on the same LAN as the PBX?

 

[ilxans]

android version 9 . smartphone samsung s8, installed 3cx version 16.6.2.89.
yes- wifi on the same lan as PBX.

Could you also please confirm what version of the PBX you are running? I can't see any activations from a V16.
Also, from your mobile app try calling *777 and try speaking into the microphone, do you hear your voice back? (*777 is the Echo Test Extension)

[EDIT]
The PBX version you can find in the Management Console --> Dashboard, on the right panel.

as there was problem with my subscription i am using this one for now

Ok,

From your mobile app try calling *777 and try speaking into the microphone, do you hear your voice back? (*777 is the Echo Test Extension)

 

[ilxans]

no absolutly no sound

 

[NickD_3CX]

First, please never post QR codes on the forum, anybody can use them to make calls!!!

I provisioned an Android Client (Android 10, Pixel 5) and the audio works fine.
So, most likely, it is something with your device.

really!? thanks. i ll try again with other phone

Hi. I have a similar problem with my Galaxy S9 with option Car Bluetooth support enabled on 3CX for Android 16.7.0.31. Only on outgoing calls I have no sound on the phone. If I tick speaker then I get sound and if I go back to phone sound is still here. If there is a bluetooth device attached there is no problem. Also when there are incoming calls it is working without problems. When I call *777 I have no sound, if I call *888 and pick up the callback I have sound.

Hi @UlrichBerger,

You can get a verbose log from the app while the issue occurs and PM me to investigate further:
a. Go into the app's 'Settings', then 'Advanced' and enable the 'Verbose Logging' option.
b. When the issue occurs, use the 'Send Log Report', i.e. the last option in 'Settings'> 'Advanced'.
c. After you select the 'Send Log Report' option, you can now disable the 'Verbose Logging' option.
