I just got a call from that number too and Avatar Tech also came up.  They asked for my husband and I said he wasn't available and asked who was calling and he hung up.   What's that all about?

I finally had to block this call on my phone.  They were calling every two hours up to 5 times a day!!  I don't know what they want but this is harassment.  It interrupts the sleep of the person I am caring for.  I now have the limit allowed, 20 numbers on my phone, blocked and new ones every week that I have to ignore.

Comes through as MMedia Spectrum just before 5, no message.

Call came in at 6:25pm Calif time on 4/17/2013. No msg left on ans machine. Caller ID displays "AVATAR TECH."

Hang up. Cid says "Media Spectrum".
