Yes, that was the first thing that I did after I realized that the phone was missing. I thought I heard someone answer, but then immediately hang up. I'd hoped that someone had found it and that I could arrange to collect it, or else that it was somewhere inside my vehicle that I can't spotted and that I could home in on the sound — I've found the phone that way before. I tried calling again and it went straight to voicemail, and that happened on several tries. I concluded that someone found it and decided to keep it.
