Need to know what this number is

I have had 2 calls from this number.  The last one I answered and I could hear ladies talking in the background.  It sounded like a Telemarketer.

Yeah I received a call from this number today - I'd say it's a telemarketer as if you ring ascending numbers e.g. 4667 5101 and upwards they have about 30 lines.  I will just be saving it in my phone and ignoring it from now on.

I am receiving repeat calls from the above phone number. When the phone rings and I pick up the receiver and say hello, the other side hangs up without saying anything.

Tele-Marketers!! GR They Annoy Me!

Called over 10 Times, said nothing.
