--------------- UX comment ----------------

The UX for merging two or more call participants into a conference is described in this spec:
https://docs.google.com/document/d/1BRy9-DEXr3A1D7PHkJaXmjbe7xbRmxKkzANXuu-F6lc/edit
The above described issue seems to be more on the implementation side rather than UX related.

It seems to be a technical and not a design issue. Added the corresponding project.

Marking as Fix Committed as bug description is updated with the UX recommendation and designs are already available.
