Phone rang 4 times at 9:41 PM on Wednesday December 23, 2020, then stopped before my landline number’s answering machine picked up. Subsequent lookup did not show a specific person or company affiliation/ownership. Carrier showed only as YMax communications. Suspect it is probably an offshore scam using this un**signed number as a lily pad to prey on unsuspecting US consumers. Nice try, but I have caller ID on my TV and will never pickup a call that does not show a person’s or company’s name.
