debian+phosh running on PinePhone

[bcnaz]

Minor  annoyance :

Phone rings on full volume for incoming call,   while already on an existing call.

call waiting normally chirps or beeps when you get a second call.

I have not tried switching to the second incoming call,  ...   has someone else... I am curious  ?

>  Not complaining,   this is as it should be, except for it being a different 'ringtone'... ?

I would rather this than no notification of a second call.
