ANOTHER scam call fom 1(209)585-1157 urging us to call 855 number. Will charge up tons if you do. Beware. Initial call and all others I have received but not answered are located on Indian Reservation lands. Never answer unless you know number. Doesn't show up on caller I'd on tv, hmmmm!

Male caller from a San Jose, CA number 408-550-1647 saying "Can be reached at 855-806-1638 and hung up. I did not call back.

Called & very brief.  Male voiceall us on behalf of TSI 855-806-1638.
I tried to pickup in time, but he hung up.

Multiple calls from 510-281-0644 (Oakland Ca) on caller ID-  Male voice leaves same message- this call is made on behalf of T.S.I- we can be reached at 855-806-1638.

" Call made on be of TSI at 855-806-1638". The caller ID for this call is actually 916-299-4211.

Received this message:  This is TSI. (855) 806-1638.

Received in loud voice this is TSI calling with 855# Call Back

Seemed that beginning of msg was cut off.
"You can call me at ( 855) ..." Loud male voice.
Nothing more. Some people are so curious that they will call back.
Maybe that's the tactic?

This is most definitely a scam call. Do not call back. It is a number for you to get charged per minute for the call. It is most definitely illegal for them to call you unsolicited. The 855 prefix is a pay to play number reserved for tech support lines and the like, it happens to be toll-free for the people calling you, however, they are getting kickbacks from the phone service such as ATT so they are trying hard to get you to call them back... don't do it.

Area Code 855 Detail (from areacodes.org)

Area code 855 is a future area code reserved for toll-free calls in which the calling party is not charged. Instead, the telephone carrier charges the cost of the call to the called party. Toll-free numbers, such as 855 numbers, have applications such as technical support, customer service, and personal use.

Got a message on my home voice mail.  Very loud male voice stating that he was calling from TSI and gave all but the last digit of the telephone number. I'm going to call him from work and give the moron hell.

I had a message on my home answering machine...."this call is on behalf of TSI 855-806-1638" that was it. I don't know who they and did not return the call. I am on the do not call list.

Called from a cell phone from Van Nuys, California at a very inconvenient time. Said very loudly "call TSI at 855-806-1638" and hung up. He called back a second time that day but I let it go to voicemail again. I am registered on the Do Not Call List, but this one violates that restriction. These noisy interruptions are quite annoying!

Called on a business line. Said this is TSI and a phone number - no message

Unknown number, said they were TSI.  Never heard of them.  Did not return call.

phone no. is unknown to me.
