It happened today around noon.
When I'm home from work, I tested with my cell phone, and it's ok (app. 5-6PM.) Also another incoming (local POST) is ok too.
It happened again since 9PM: the phone rings, I pick it up and hear it well, but my sis. doesn't hear me(its' a local cell number). She calls on my cell to let me know. Then I call another number in LA (Verizon voip/fios,) same thing, It's ok on ooma end, but the other end does not hear nothing.
ps
I just said I'm a happy camper yesterday, is there a jinx?
Edited
It's one defected handset of the new Phillip Dect 6.0 cordless, will return it.
