Choosing the Right Free IVR Software

There is significant overlap in the features offered by the free IVR software solutions available today. However, there are some clear differentiating characteristics of each platform.

What may stick out most to the customer service manager hoping to implement a free IVR software solution is that the above solutions vary in just how free they really are. You may opt for a more hands-on, totally free experience such as Ekiga. Or, perhaps you just want a free trial of a premium service like Zendesk Talk.

The IVR software you settle on will largely depend on the size and ambitions of your team. Thankfully, there are a number of free IVR software solutions to try out before you need to make your final decision.
