Based on the available information, it appears that the caller with the number +17604047901 made a call that was not answered by the recipient. The caller's identity and purpose are unclear, but the fact that they are supposedly from a Californian number suggests that it could be a robocall, a telemarketing call, or a scam call. The recipient's decision not to pick up due to not knowing or dealing with anyone in the USA implies that the call may not have been legitimate or relevant to them. Overall, the caller's intentions and identity remain unknown.
A call claimed to originate from a Californian number; I didn’t answer since I have no contacts in the USA.
