When it walks like spam, talks like spam --it's definitely spam!
You answered your own question --cold e-mails with phone numbers are triggering the spam filters.

cold e-mails with phone numbers are triggering the spam filters.

All of the cogs in the email wheels today are setting up more stringent architectures and policies regarding email practices. While there are some B2B allowances on the cold email front, it is just a DUMB practice, IMO. Honestly, with a good micro niche funnel that provides constant valid and valuable information and opportunities, a marketer can kick ass collecting emails and build awesome lists that respond and bring earnings.

It's the "lazy" marketer with only short term hit and run tactics that wants to get into the cold email practices.
