Mutualser EPS members, booked on ViSof. With Arbol, on your line and WhatsApp.
How it works
The Mutualser EPS member calls or writes to your organization.
The assistant asks for the Mutualser EPS order and authorization before offering a slot and prepares the case for your team if something is missing.
It books on the ViSof calendar, with the real availability of each clinician and site.
The appointment shows up in ViSof like any other, and the conversation stays on record.
