As HubSpot's official integration partner, Red Cactus is introducing a new feature to its existing telephony integration called Bubble. As of now, Bubble is also available as a "calling provider" within HubSpot.
Long story short, it means that as of now you can link +50 telephony platforms to the telephony functionality within HubSpot. This allows you, for example, to easily dial out using the official telephony icons within HubSpot with 1 click of a button without incurring additional telephony costs. Everything simply goes through your own telephony environment.
Until recently, this was only for a few specific telephony platforms, but no generic 'provider' was available. With Bubble, that is a thing of the past and you can connect virtually any telephony platform.
