    Hi Carl-McDowell - thanks for this article - you mention that "by default, long code numbers cannot receive messages from short code numbers" but can this be adjusted in Zendesk settings somewhere?  We receive short code numbers to our mobile phones (long code numbers) for other MFA services, so it must be possible, right?

    Hi Joe,

    Unfortunately, there is no setting that can enable this in Zendesk. I understand that this works outside of Zendesk but as stated in the article, it is not possible in Zendesk to avoid any security breach when receiving short codes like OTP and security codes.

    Thank you.
