Go out and do a Google search on # 213.999.9999.

It is a number that Telemarketers are using to mask their true CLI, as it is presumed to be an invalid/unused number. Unfortunately, some poor chap owns the cell number 213.999.9999 and is now on the receiving end of 100's of irrate call-backs wanting to know why he called them in the 1st place.

Time for a new cell number, my man.

Getting calls from this number. Found that it's T & L LEASING(LAI). I have no idea who they are and why they are calling my number.

T&L Leasing appears to be a faked number used on caller ID.  There are NO area codes that use the phone number 999-9999; it's just one of those that are never issued.
We have received several calls from people using that number on their caller ID, either asking us for information on our network to updat their 'database' - just say no! or wanting to sell us toner supplies.  They offer to send free samples then bill you an outragious amount hoping your accounting department will simply pay the invoice.  When I tell them to send us a price list and company info so we can put them on the approved vendors list they just hang up.
Yup, it appears to be a total scam.
