Receive Call Transfer Requests in Slack


We're excited to announce that now integrates with Slack, a widely used, cross-device messaging and collaboration tool. Your receptionists can now send incoming call transfer requests to a designated Slack channel, so no matter which device you're using (computer, tablet, or phone), you never miss an opportunity to take a call.

What is Slack and How Does It Work with

Slack is a chat communications platform for businesses big and small. Slack can be accessed in any browser and through its desktop and mobile apps, so no matter where you are, you can always collaborate with your teams and colleagues. Over 1,000 SaaS partners integrate with Slack, and we're proud to say is now among them.

What this means for clients is that live call transfer requests can now come to you via your phone, tablet, or computer. 

Previously, call transfer requests could only be handled by ringing you directly. But phone calls aren't always the best means of notification. Perhaps you're often in areas where phone service is spotty, you're in meetings with your ringer off, or you find yourself in other scenarios where picking up your phone to respond to a call transfer request is not possible or just not ideal. Or, perhaps you just prefer to reduce the disruption of your phone ringing when you can just as easily receive a Slack notification.

With a dedicated Slack channel for call transfer requests, when you receive a call that meets your call transfer guidelines (a VIP client, a potential new customer, a business partner), your receptionist will send a notification that you'll be able to see on all of your devices, as long as you have an internet connection. All you need to do is accept or reject the call by clicking a button. Throughout the entire process, your receptionist will remain on the line with the caller, so they're never put on hold awaiting a live transfer to you, which we believe delivers a superior experience.

Receiving call transfer notifications from in Slack is as simple as emailing us your workspace link, creating a dedicated channel for, and then authorizing to communicate with you in that channel.

  3. Create a channel for your team to receive incoming call notifications, e.g., #smithai-notifications

  5. Log in to your Slack workspace:

  1. Click "Done"

All set! You'll see notifications from every time a call comes in that meets your "live transfer" criteria.

How to Respond to Slack Notifications

As soon as we determine a caller meets your "live transfer" requirements, you'll see a notification that looks like this in your Slack channel (name, phone number, reason caller wishes to speak with you):

Approve a call transfer request

Click "Yes" to approve the transfer request and have the call connected to you.

Deny a call transfer request

Click "No" to deny the transfer request and have your receptionist handle the call.

What happens if we receive no response

If we do not receive a "Yes" or "No" response within 30 seconds, we will assume you are busy and will not attempt to transfer the call.
