DS01 is a bundle which includes PL11 (door sttaion), PL71 , PL81, RGR05 ringer and DM02DM01 should not affect the audio quality
Do you have Comfort 2, not Comfort 1?
You should upgrade the tuning parameters. Open a new file and write selective > select tuning parameters and write to comfort
That should improve the performance
I’ve uploaded the tuning parameters and the volume of the person at the doorcstation whobos speaking, is really very quiet on the internal phone handsets
Any idea which tuning parameters I should play with, or do I need to do something with shunts?
The metal doorcstation replaced an old DP03X which worked just fine. Can I just swap them out of so I need to change something on The DM01?
J6 is not needed on old versions on DM02 as it is shorted in hardwareCan you check what are the shunts on the board, or take a high res photo of your DM02 so we can check which version iyt is
