Since the recent update for the RingCentral desktop app from 19.8.1 to 19.9.1, setting the new Outbound Caller ID for Texts option to your Main Company number does not work. The option is visible and selectable, but will not send SMS from your Main Company number. Texting from the Main Company number works from the RC Phone app and the RC SMS API but does not work from the new RC desktop app, even if you are working from the operator extension.
