Yes, CallRail can identify voicemails when a customer leaves a message on your own system: New Feature: Voicemail Detection
But what about outbound calls? We have a call center which leaves voicemails on customers’ machines when they do not answer. These are hard to quantify or tag, because there is no duration patter or keyword to spot for.
How about CallRail just listens for the “beep” tone, the same exact way as a keyword can be spotted? That way, an automation can be implemented to tag it.
