It's a voip service isn't it? Those numbers will not work with many online services and even some more obscure normal providers.

Basically everything is VoIP these days (VoLTE, etc.). Online services sometimes have secret lists of phone numbers they don't like, but "voipness" isn't a silver bullet for determining whether or not a service will like your number or not. The JMP people wrote more about this at https://blog.jmp.chat/b/2022-sms-account-verification

Anyway, this thread is about Signal, and JMP numbers work with Signal, which is why I suggested it.
