I don't remember about "Call as"# on screen, because since yesterday (appreciate your prompt reply), I chose to acquire a new GV phone# using my unrelated cell phone, by which I could then reset PIN as well. But when I tried to link the new GV phone/acct# with my old landline/Obihai#, a red high-lighted message appeared,"This [landline] phone# can't be used to verify a new account because it's [already] managed by Google (eg Project Fi, Google Voice). Try verifying with another number." So my new acct/phone# is linked only with my cell phone, which is useless for porting out purposes, and yes, it does now show "Call as"-new GV phone# on opening screen. I just deleted my new GV phone# and opening screen no longer shows "Call as" anything. I then tried using my landline# to obtain a new GV phone# but got the same red message as above.
