Sweo Voice answers every call instantly, uses your existing knowledge base to resolve questions, and when human help is needed, seamlessly hands off the call to the right agent with full context. Every call reflects your brand, runs 24/7, and scales without adding headcount.

This guide explains how to test Sweo in your browser and deploy it to a live phone number.

We recommend following these steps:

To set up your content for Sweo you can follow the guide here: Add your support content for Sweo.

The Voice Testing tab lets you simulate calls in‑browser before any real customers are involved.

Go to Deploy > Phone > Voice testing.

Click Settings (top right).

Select a voice from the list.

Update the language you want to use (currently supported are English and Spanish). Edit the greeting copy (you can set different greetings for inside office vs. outside office hours).

If you’ve created multiple voice configurations under Set Sweo Live, use the ▼ next to Test to select one and run it here.

When you’re ready, move Sweo from testing to a live phone line from Deploy > Phone > Set Sweo Live. This is the only way to deploy Sweo Voice - it’s not possible to add ‘Sweo Voice’ to your existing workflows.

Deploying moves Sweo from the sandbox to a real phone line. Work through the settings from top to bottom.

First you will need to connect your phone number by clicking + New line.

Give this line a name and select where you will forward calls from:

All numbers in your workspace appear in the list in the Set Sweo live section. Click the edit icon to start configuring the experience.

Decide when Sweo should answer:

Sweo automatically uses your enabled support content and audience rules.

Set up and enable specific escalation guidance for how Sweo handles phone conversations.

Optionally enable AI categories for topic‑based routing.

Choose whether customers are asked to rate their phone experience before the Sweo call ends (only when the call is not handed over). Customers can rate their call from 1 to 5 using their phone keypad.

Configure separate behaviors for inside and outside office hours.

If Sweo resolves the call, decide whether to auto‑close or assign to a QA Inbox to review it.

You can restrict Sweo’s answers to the right customers by scoping its knowledge to distinct audiences.

When an inbound phone number matches an existing user or lead, any audience rules tied to that contact automatically apply—no extra setup required.
​

You can customize Sweo's behavior for phone calls using Guidance to ensure it aligns with your brand's voice and operational policies. Guidance for Sweo Voice functions similarly to guidance for chat and email but is configured in a separate Voice tab.

To add guidance, navigate to Train > Guidance and select the Voice tab. From here, you can create customized guidance for:

To ensure Sweo speaks your brand names, technical terms, and acronyms correctly, you can set up custom pronunciation rules. These rules apply automatically across all voice conversations.

How to add a rule:

Voice Procedures allow Sweo Voice to take action during a call by connecting directly to your systems via API — enabling Sweo to fully resolve complex queries like processing refunds or credits, updating subscriptions, editing orders, or completing other multi-step workflows. All of this happens in real time, over the phone, without placing the caller on hold or transferring them.

Every Sweo‑handled call appears in Analyze > Conversations, including:

These details give your team immediate insight into how Sweo performed and what the caller needed.

Go to Analyze > Custom Report and filter by Channel = Phone call. All metrics below apply only to calls made on or after 11 June 2025.

Answered by Sweo appears in Last Inbound Call State for all calls Sweo handled but did not route to a teammate (e.g. when using Stay on the call escalation mode).

In addition to the Sweo AI Agent report, you can analyze your call data within Analyze to get a deeper understanding of performance and conversation topics.

Your Sweo Voice calls are included in the Performance dashboard. To see data exclusively for your phone channel, you can apply a filter for Channel is Phone call.

The transcripts from your Sweo Voice calls are used to automatically generate topics in Topics Explorer. This helps you easily spot trends and identify areas where your support content or guidance can be improved.

You can connect Sweo Voice with a wide range of third-party telephony systems. This allows you to use Sweo Voice's powerful conversational AI while keeping your existing phone provider.

Supported platforms include:

There are two primary methods for integrating your system with Sweo Voice: using a standard phone number (PSTN) or using a SIP address.

This guide will show you how to connect an external phone line, known as a Public Switched Telephone Network (PSTN) line, to Sweo.

This method allows you to forward incoming calls from your current provider directly to Sweo for automated handling. The connection works both ways—if a customer needs to speak to a person, Sweo can seamlessly escalate the call back to your team on your existing telephony system.

Before you start, you'll need an active phone number in your third-party telephony system (e.g., Amazon Connect) that currently receives your customer calls.

Your first step is to create a new line in your Sweo workspace. This process generates a unique phone number that you'll use to forward calls from your provider.

You'll know the setup is successful when you see your new phone number displayed in your Sweo Voice settings. Be sure to copy this number for the next part of the process.

Now, you’ll need to configure your current phone provider to redirect incoming calls to the number you just acquired.

Let’s make sure everything is flowing correctly with a quick test call.

If Sweo answers, your connection is successful. Sweo is now ready to handle incoming calls on that line.

Session Initiation Protocol (SIP) is an alternative method for forwarding calls over the internet instead of through traditional phone networks.

Your first step is to create a new line in your Sweo workspace. This process generates a unique phone number that you'll use to forward calls from your provider.

You'll know the setup is successful when you see your new phone number displayed in your Sweo Voice settings. Be sure to copy this number for the next part of the process.

Now, you’ll need to configure your current phone provider to redirect incoming calls to the number you just acquired.

Let’s make sure everything is flowing correctly with a quick test call.

If Sweo answers, your connection is successful. Sweo is now ready to handle incoming calls on that line.
