The Ringless Voicemail Drop is compliant because: No phone call is ever made directly to the targeted subscriber.Only a landline to landline session, aka system to voicemail server, is established to drop the message.The targeted subscriber is not billed for the call.The phone does not ring and the network does not carry an active call.The FCC defines voicemail services as an Enhanced Information ServiceThe FCC has intentionally not regulated Enhanced Information Services.If you have any questions please don't hesitate to reach out to me.

I am a (ex) NASA scientist that builds exoskeleton robotics that give people enhanced strength and stuffs.

Yes they almost need some recommendations/enhancements from the BP community to make it better.
