Check your codecs order everywhere:

- Settings > General
- Extension > Phone Provisioning > 3CX App
- Extension > Phone Provisioning > Yealink T4...

Make sure all the same are set, and in the same order.

 

[bruceleeon]

So, delete anything that doesn't match, and make sure they are in the same order? Just want to verify before I delete things

 

[Evolute IT]

Just put the 4 first to be the same on each page.

Settings > General will not allow you to delete the others so just put them lower.

Done, No change.

Did you reprovision the phone and the android app?

On each device, make sure there are connected to the 3CX server - dial *777 which is the echo test.

[bruceleeon]

It works Thank you... I had read threads that referenced codecs, but never saw the "same order" piece

 

[AWS2P]

prefered order is to stick SIP provider order
