[VoiceOps] VoIP is a restricted business?

Hello, Happy New Year everyone. I recently became aware of the fact that banks (and financial institutions) define any business that merely mentions the word VoIP as restricted. Meaning they would not allow such a business to work with them. As if VoIP is some kind of an illegal substance. I am confident that when it comes to larger players they are not defined as a VoIP business... One company (Wise/Wisetransfer) even claimed that their regulation requires them to do that. I wonder if you have any more information and how do you deal with this. Thanks, Oren
