Unable to make Volte call from z5 premium dual E6883

[Santosh-Aher]

Tried below options
Software repair
Selection of lte mode.
Turning on Volte provisioning flag.
Still not able to place a volte call using default phone app.
Current build version is:32.2.2.A.0.253

Which default app? is your phone network branded? test it in >>> safe mode

[Santosh-Aher]

The default sony "Phone" app.

Yes, I am using relince jio network which supports VoLTE calls.

Tried safe mode as well, still not working.

Finally It worked.

I found that the firmware which is installed on my phone was the Singapore version.

Device: Xperia Z5 Premium dual (E6883)
CDA: 1299-2163
Market: Singapore
Operator: Customized SG
Network: GENERIC
Version: 32.2.A.0.253 / R7C

So I just flashed the indian version FTF and bingo !!! It worked.

Device: Xperia Z5 Premium dual (E6883)
CDA: 1299-6238
Market: India
Operator: Customized IN
Network: GENERIC
Version: 32.2.A.0.253 / R6C

Now I can see
1. Notification as "Device is HD capable".

2. VoLTE Icon in status bar.

3. Enable VoLTE option in Mobile networks.

And now I can place a call from sony's default phone app, which shows the option for video call as well.

Thanks,

Santosh Aher.
