This number calls before 09:00 hrs. each morning and several times during the day including after 21:00 hrs.  If this is a collection agency, it is my understanding that they are not allowed to call before 09:00 hrs. and after 21:00 hrs.  I will be reporting them to the California Attorney Generals Office and any other entity who can stop this unknown calling which leaves no message.

call them back and tell them not to call you. i did...no more calls.....

I receive call constantly from this number with no message. It appears to be a collection agency.

Calls come in every day , sometimes several times a day from this number.  They leave no message as to
what their business consist of or their reason for calling.  I'm in the process of reporting them to the California Attorney General"s office.  Perhaps this will stop their calls.

Called my cell phone and hung up when I answered.
