Hi,
I came across a very strange case on my Nokia 8. I use the T-Mobile network in Poland.
When i calling to a user from one specific network (Play) This user talking from Smartphone Sony. After few minutes of call i always lost EVS codec only on my Side after few minutes of call. Other side still hear very good quality EVS.
It is very interesting that Network Signal Guru constantly shows the EVS 24.4 codec on both sides. Any other providers working very Good when i call to it. Play Mobile use Huaweii RRU.
In both cases, the signal is very strong. It is not dependent on location. It always happens only with that one network and Sony or Motorola phones.
Any Solution?
