Caller ID issue

Hi there, we've got an issue with multiple tenants/customers with their outgoing callerid.
I've created a new CallingLine identity and assigned them to the users, using PowerShell.

Reason? The customer want’s to use the company’s main phone number for outbound calls. But when making outbound calls to varies Dutch providers, the main phone numbers is’nt showing up, but the personal user number is. When making calls to other Skype for Business users, the main number, does show up.

-I’ve removed the calling plan, and created news one’s but the problem remains.
-When assigning Anonymous callerid, is works perfectly.
-We use PhoneSytem, cloud only with Office 365. So no hybrid environment.

I’ve had contact with Microsoft support and with the Skype for Business porting desk. They both respond the same. The issue is not Microsoft it’s problem, but lies with the CNAM of the Dutch providers. I’ve tested it by making calls to Vodafone, KPN and T-mobile. All gave the same result. Not the main phone number is showing up, but the users personal number.

Anyone else experiencing this issue? Microsoft is using Colt Telecommunications, perhaps i need to ring their doorbell...
