From a design/engineering perspective I get this... i.e. Yealink never thought of this requirement and so designed the phones to only have a single DSP that handles all audio. When you're on a call the DSP is busy processing the voice traffic and so cannot be available to generate the ringtone on the speaker.

From an end user perspective though this seems like a pretty big oversight. I am surprised that with all the hardware changes over the years nobody ever thought to properly solve this problem by adding an additional chip or hardware channel to allow the speaker and handset to run in parallel... surely these days that couldn't represent a huge cost factor to do.
