This is a scam phone number

Caller: Ryan

Asked for specific people by first name, claimed to have spoken with them recently to have a follow up teams meeting. Advised he had lost the specific persons number and could we provide it

Caller: Ryan

Do not answer this number.
4 June, 3.24pm - Caller asked for the owner of our business (tried to pronounce the name) and said he was just talking to her, and was asked to call back. It didn't feel right to me.
As our business owner was in a meeting, I knew the caller was lying.
He said his name was Ryan and asked if I was a business partner. Then he asked for our owners direct number because he "didn't have his diary with him". I explained he had just called the direct number... that confused him (hahaha).
I could hear lots of noise in the background (like a call centre). When I asked to take a message he left his number 0482 081 373, but didn't say what it was about.

Caller: STR Marketing Co

Ryan from STR marketing. He said it was about Google Ad. Asking for personal mobile number. SCAM call.

Caller: Ryan - CT Group

I constantly get nuisance calls from CT Group today it was from Ryan - talks non stop, claims not to be trying to sell anything, but goes straight into his long winded pitch to upgrade websites etc.
I have told them EVERY call (30+ times now) to remove me from their database, even yelled last time, but they keep calling.
Scammers

Caller: Ryan

Very persistent in selling me something I don't want.

Called twice in 5 minutes , left no message

called twice didn't leave a message, appears to be a scam caller.

Caller: Lee (Male)

Asked for specific people by first name, claimed to have spoken with them recently. Says he's from "Education Supplies". Suspected scam.

Caller: Lee / Leigh (Male)

Asked for a specific person (by first name only, which is public info) but refused to give any details of where he was calling from, nor the nature of the call.
Strongly suspect scam with phishing elements.
