We added an employee Tampa (Audrie) and one in DC (Rachel) with a 727 area code, respectively. With our MN employee when she sends out a conference invite, her conference calls have a 612 area code. same as her phone number.
The Tampa and Dc employees show 412 conference numbers when they send invites. I would like their conference lines to match their area code.
