I just received a call from them, asking for the homeowner. After looking at the very unprofessional pic on LinkedIn, I am glad I said I was not the homeowner.

Telemaggoter Call: February 12, 2015

This would appear the second call from this alleged number. I realized these characters are desperate to make new friends. But I am not.

I looked up the Sipcom PLC website.  I think that if we pepper them with emails telling them to take us off of there list as many times as we receive there annoying calls maybe they'll get the hint and tell whatever telemarketing company handling their calls to STOP CALLING US.
Anyway, that';s what i'm gonna do everytime they call.  Send them an email.

btw:   www.sipcom.com is their website....pepper them with email to STOP CALLING and maybe they will get the hint,

Received a call from this number 718-285-3924 on Monday 12:42 pm, missed the call.  I did not call back at first and no message was left.  I just called and the recording said this number is not in service.  This is obviously a scammer who uses the phone for a short time and throws it away or changes numbers.
