Missed call. Rang back from anonymous phone and after a long pregnant pause the number was busy. Sounds a lot like a New Delhi call centre working for Skytech sales and marketing in Northcote in Victoria that sells Vic Gov't approved solar panels and hot water etc. They use random number generated id so a number is displayed on your phone but it is a phantom. I save them and have about 100. I get the occasional repeat. I try to waste as much of their time as possible until they give up. They still will not take me off their list.

Caller: Solar panel scammers

Overseas call centre scammers. When told the owner of this phone is now deceased and not to call again the operator pushed and demanded to speak to the homeowner regarding the scheduled solar installation. Once I retorted they ended the call. The company name she quoted was mumbled and unintelligible. Do not trust calls from this number.

Came up with 'suspected spam', just let it rang out.

Ring then hang up no contact
