Hi,
We have a working solution for connecting Rasa bots to telephony channels by using AudioCodes Voice.AI Gateway solution.
This can be useful for contact centers and enterprises. It enables routing a phone call to a bot, and in case the bot cannot assist, the call can be transferred to a human agent.
We’re using STT and TTS for communicating with the caller. Communication with the bot is text-based. We support Azure, AWS, Google, Yandex and Nuance providers.
The solution was integrated recently in Google Dialogflow.
There’s a pull request adding the channel for Rasa here.
Can this feature be useful for you?
