Who called from 6235526443

We have been receiving calls from this number daily. Each time they call, they never leave a message and their calling system messes up ours so that we have to reset it. Tried to call phone number back but its not real working number since it goes to a busy signal. Believe these are another set of scammers..

We have received calls from this number leaving voicemails that contain only static.

keep receiving incoming call to these number ,no one answerring & its a died #

Getting calls at 3am from this number, only hearing static. If someone gets a hold of them, please tell me how.

Calls through the system to reception, nobody on the line, no recording, just dead air.
