+1 on this. All mobile carriers I've worked with allow this, would be a nice feature.

@Erik Jacobsen For a new feature request please put your idea here: https://ideas.ringcentral.com/

If the idea already exist you can vote that idea there. That will help to make it implemented in future

You may have better luck placing your message in a tightly sealed bottle and tossing it in the Pacific Ocean.  Messages tossed in the Atlantic ocean may take sufficiently longer to reach Washington State, but most are then forwarded to the Phillipines.  As you can see, its been six years and they still have not received it.  Please just be honest and say “It ain’t never gonna happen, no way, no how” versus the false hope wasting time in the ideas forum.
