Calls echo audio while calling
What problem did you encounter
Having audio calls with other cellular phones seems to echo back the non-devkit caller voice quieter and a few seconds later.
What is the actual behaviour?
non-devkit caller getting echo of their voice
What is the expected behaviour?
No echo of voice
How to reproduce
- Call or be called with a devkit and another phone
- speak into the devkit, all works
- speak into the other phone, it is heard by the devkit, but also quietly and a couple seconds later echos back whatever was sent to the devkit.
NOTE: Yes it seems strange, this was tested on three different "other" phones with three different numbers to/from the devkit with the same echo result. It is almost as if the other phones audio comes into the devkit and then sends it back quieter to the other phone again.
