We have request from our cloud PBX customers:

There is currently not easy way, to create a new entry in contacts app from an existing call number entry in call list (phone-, softphone, call list-app…).

Copy and paste has to be used.

Request is, to have an additional button below call list entry, that opens contacts add/edit-dialog filled with well formatted call umber of call list entry. After completing this contact dialog, a new contacts entry is created (personal address book is selected by default).

This is not a new request. See also here:
