I have done some research and traced this number to Silver Strand Ent,LLC, owner Thomas W. Luczak.
After googling his name, this is what I came up with: His home address is listed as 29009 Silver Creed Rd. Agoura Hills, CA 91301.  It lists his number as    808-865-9444.   I have tried the number numerous times and keep getting a busy signal.  Maybe many others, like me, are tired of his telemarketing calls and are calling him to get back at him.  See how he likes being disturbed on the phone.  Anyway, I am trying to get through to him to see how it likes it.  If you are angry at him, try calling him at the number above.

Other phone numbers that Silver Strand Ent is calling from is : 626-668-8221, 702-705-5287& 408-880-8250

Their phone calls come on my verizon cell phone.  They are getting very annoying.  ,My number is listed on the National DO NOT Call list, but that doesn't seem to matter.

Keep getting these calls daily, wish they would go away. I have began rejecting the call, first few were telemarketers

call each day.don't know anyone in calif

Many thanks for your information.
I am also getting calls from 408-880-8250.

They call me several times a day and if i answer they just hang up. Ive tried calling the number back and it never rings... it just hangs up my phone. I dont know who they are!

They call me every single day. If you try back you get a message about not being able to complete your call. Must be using number spoofing or something. Annoying as hell.

I get a phone call from this number on a daily basis. No one answers when I pick up

I got a call from this number and it said it was Mark Sager from Dental Services. I said "Who?" and it took a beat or two before the robotic voice said Mark Sager then I realized it was a voice activated system so I hung up. I got enough to do and I'm not so lonesome that I need to talk to a robot.

Every day in the AM and PM I get a call from this number and they never leave a message.  I don't answer as I am at work and don't recognize the number but am tired of it ringing!

Whoever this number belongs to, stop calling or I will turn this over to law enforcement.

I will report this number to law enforcement if I receive anymore calls from this number.

Been getting these types of calls for a year on our landline. Keep telling my Mom to call the phone company and investigate it. Sometimes I'll answer these strange numbers & it'll be a friend or a family member on the line. Sometimes family members have to call 10+ times just get through to us. Sometimes, during phone conversations with friends and family members, the call will be dropped. And when either I or whoever I was talking to calls back, it'll show up as another number and you can hear echoes & clicks. Sometimes you'll hear random strange beeps. And on one occasion, my sister called our phone only to have some foreign guy pick up (not us, we weren't home), say, "Hello" and you could hear another guy in the background talking and it would repeat over and over - like a looped message. She recorded it. She checked the number she had dialed on her cell & sure enough, it was our number and not a mis-dial. She then called and left a series of messages on our answering machine, frightened, thinking someone was in our house. I've got all the evidence up on my youtube channel. /watch?v=meOOcHZWRxE

Absolutely bizarre.

This particular number showed up as "PINNACLEHEALTH" and when I answered a man said, "Hello, this is Mark Sager calling from Dental Health Services. How are you doing today?" I'd received similar calls from these type of numbers & decided to try to play along to get more information. So I said, "Good. You?" There was no response. I realized that the voice was not a man, but a robot. That sounded A LOT like a real person. +1 brownie point for the creep factor.

So, I waited until it disconnected me before hanging up. I googled the number & found several of these websites full of strange reports regarding this number. After I redialed, the number didn't ring, but I could tell I was being recorded. So I gave them quite a show and began reading off some of the people's complaints in random sing-songy voices. It went on for a good 5+ minutes before I was disconnected. So I redialed and got a busy tone. So I kept calling and calling until it started to ring. It rang for a while before going back to the busy tone. So I called a few more times & started getting the, "This phone has been disconnected..." right away, or "This call cannot be completed as dialed..." After a while, it kinda lost its luster, but I am tempted to call back one more time. Just did. Busy signal. No surprise.

I can't help but think there is something really strange going on here. I've been keeping a list of these numbers & their caller ids. I hope this helps anyone else who may be having the same issues:

Has called me every day for weeks. Is not a real person and every time I ask for one to take me off the system, the call hangs up.

Started getting these calls a couple weeks ago on my cell phone. I haven't been answering them due to I don't know who it is. No message is being left. After sending a reject message early last week, they are coming in 3-4 times a day now.

I am also getting called a few times a week from this number and have been called by 62666688221.  I never answer, and I am also on the do not call list.

whose number is this?

Please make them stop calling...no one answers when I pick it up and they are using my cell which is on a do not call list!!!!!

I've received several calls from this phone number.  Please make them stop they are burning up my minutes.

EVERY day  call from this number 408-880-8250 ID Pinnacle Health - no one on the line. How do I stop them?

This number has been calling for the past few days and leaving no message. Called back and message said it was a non-working number!?!? WTF

I get several calls a week from this number, on my cell which is on a do not call list, but they hang up when I answer. Calling back only gets me a busy signal..

I didn't answer since I didn't recognize the ph number. PLEASE MAKE THEM STOP!

this number keeps calling me, never leaves a msg.  i called it back from my work phone and it rang several times finally connecting me to an answering machine with a womens voice saying she cant answer the phone and to leave a msg. very shady.  i dont know anyone in california so hopefully shes just dialing a wrong number.

I have gotten calls from this number repeatedly! I dont answer since it isnt a number I recognize.  They never leave a msg either, very annoying!
