got call from this number. no message left. the caller number showed on my phone screen was "1-310-554-65522". i don't know why there is an extra "2" after 310-554-6552.

Probably another spoofed number, another three ring hangup.

Same criminal gang. Just a new phone number. This criminal organization is supported by our politicians, who share in the profits of crime. Nothing will be done in California to stop these criminals. These criminals exist due to the support of our corrupt politicians and greedy telephone companies, both of which receive significant amounts of money from these criminal enterprises. It would be so simple for the phone company to identify all unused phone numbers by marking them as "invalid number" as part of the "caller i.d." program. But, the phone companies elect not to identify invalid numbers since they earn substantial income from these criminals calling us every day. Such is our life in California. Criminals, politicians and the phone company share common interests.

Caller didn't leave a message. CID said CMTN CMTN CA and the phone number had too many digits 131055465522. This is the closest number I could record a report. This number represents an international caller. At any rate this is just another scammer that needs to be blocked.

Caller ID: CMTN CMTN CA  Machine answered, no one spoke, and then hang up.  Call center heard in background.  Same as above, long number of 131055465522 displayed on caller id.
