On March 1, 2021, we will be removing the Voice Agent with Watson service from the IBM Cloud catalog. Don't worry though, it's not because it failed, it's because it was so useful that we have now fully integrated it into Watson Assistant as the newly released phone integration!
There's very little effort to migrate, and a ton of value to be gained. Now that it's built in, you get to use Speech to Text and Text to Speech for free through the phone integration, and you simply pay per Monthly Active User - no more complicated usage calculations or estimating numbers. If Watson talks to a user within a given month, digital or on the phone, no matter how many times, it only counts as a single MAU. (Assuming you have a way to correlate user_ids across channels).
To migrate, simply add your Voice Agent phone number to the Watson Assistant phone integration, and copy the new SIP endpoint from the Assistant phone integration page to your telephony provider, similarly to what you originally did with your Voice Agent service. That's all it takes!
There's a lot more coming that will make everyone's lives easier, and a lot more investment in making a unified experience when creating assistants deployed on the phone, as well as deploying a single assistant across multiple channels.
Note that anyone currently using Voice Agent with Watson will still be able to use the service unaffected until December 31, 2021. If you have any questions or concerns about timelines or migration efforts, don't hesitate to post your questions here in the IBM Community for our team to lend support, or email me directly at firstname.lastname@example.org .
Thank you for all of your interest and dedicated to Watson services, we can make improvements like these because of valued customers like you.
