Transferring to VM using Yealink T57@

We just received a desktop phone through Ringcentral (Yealink T57W) and I don’t see any feature to transfer callers to an employee’s voicemail.  When using the Ringcentral App, there was an option to transfer to vm when the employee was on a call.  Is there any way to transfer calls to vm using the Yealink T57W desktop phone?
