# Integrating voice assistant with CCaaS provider

Enable users to get voice-based support from ServiceNow AI voice agents by integrating ServiceNow voice assistant with supported third-party Contact Center as a Service providers \(CCaaS\).

When you create or edit a voice assistant, you configure communication channels to define how the assistant connects to users. Select a **Provider application** to deploy the assistant to — this field is required for all communication channel types and appears above the channel tabs.

Communication channels are organized into two tabs:

-   **Telephony provider** — connects the voice assistant to a phone network.
-   **Web Real-Time Communication \(WebRTC\)** — connects the voice assistant to mobile applications.

**Note:** To configure a telephony provider, select a communication channel type from the **Communication channel** drop-down, then select a CCaaS provider. The available CCaaS providers depend on the selected channel type. To remove a linked provider, select **Unlink this provider**.

## Telephony providers

The following sections describe the configuration fields for each supported CCaaS provider under the **Telephony provider** tab.

## Twilio voice service \(WebSocket\)

|Field|Description|
|-----|-----------|
|Authentication Token|Authentication token to authenticate to your Twilio voice service account.|
|URL|Read-only. Autogenerated URL to connect Twilio voice service to the voice assistant.|

## Genesys voice service \(Audio Connector\)

Genesys uses the Audio Connector integration and the WebSocket channel type. After the configuration is saved, copy the generated credentials and paste them into your Genesys Cloud account to complete the integration.

## Genesys voice service \(SIP\)

|Field|Description|
|-----|-----------|
|Transfer number/address|SIP URI to transfer the call to the Genesys voice service. Use the format `user@domain`, where the user part is up to 16 characters and the domain part is up to 256 characters. URI parameters are not supported.|
|Transfer method|Read-only. Set to **REFER** for Genesys voice service.|
|ServiceNow SIP Trunk information|Read-only. The ServiceNow SIP fully qualified domain name for your region, used to route calls from Genesys voice service to the voice assistant. For configuration details, see [KB3023612](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB3023612).|
|x-snc-param|Read-only. Generated token to send to your Genesys CCaaS account to authenticate requests to the voice assistant.|

## Amazon Connect \(PSTN\)

|Field|Description|
|-----|-----------|
|Transfer method|Read-only. Set to **BYE** for Amazon Connect.|
|Call context API|Read-only. The URL that Amazon Connect uses to send call context data to the voice assistant.|
|Client ID|Read-only. Generated client ID for OAuth2 authentication of call context requests from Amazon Connect to the voice assistant.|
|Client Secret|Read-only. Generated client secret for OAuth2 authentication of call context requests from Amazon Connect to the voice assistant.|

## 3CLogic \(WebSocket\)

3CLogic uses the WebSocket channel type. After the configuration is saved, copy the generated credentials and paste them into your 3CLogic account to complete the integration.

|Field|Description|
|-----|-----------|
|URL|Read-only. Autogenerated WebSocket URL to connect the 3CLogic voice service to the voice assistant. Copy this value to your 3CLogic account.|
|Client secret|Read-only. Generated client secret to authenticate requests from 3CLogic to the voice assistant. Copy this value to your 3CLogic account.|
|Client id|Read-only. Generated client ID to authenticate requests from 3CLogic to the voice assistant. Copy this value to your 3CLogic account.|

## Five9 \(SIP\)

|Field|Description|
|-----|-----------|
|Transfer method|Read-only. Set to **BYE** for Five9.|
|ServiceNow SIP Trunk information|Read-only. The ServiceNow SIP fully qualified domain name \(FQDN\) for your region, used to route calls from Five9 to the voice assistant. For configuration details, see [KB3023612](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB3023612).|
|x-snc-param|Read-only. Generated token to send to your Five9 account to authenticate requests to the voice assistant.|

## NICE CXone \(SIP\)

NICE CXone uses the SIP channel type. Enter the NICE API credentials from your CXone account, then use the generated ServiceNow SIP Trunk information to configure the SIP trunk in CXone.

|Field|Description|
|-----|-----------|
|API endpoint|The CXone API base URL. Must be a valid NICE domain, such as `https://cxone.niceincontact.com` or `https://cxone-gov.niceincontact.com`.|

|x-snc-param|Read-only. Generated token to send to your CXone account to authenticate requests to the voice assistant.|

## Custom \(SIP\)

Use the Custom provider option to connect the voice assistant to any SIP-capable telephony system that is not available as a named CCaaS provider. Inbound calls arrive over a customer-provided SIP trunk and are handled by the AI voice agent.

|Field|Description|
|-----|-----------|
|Transfer method|Select **REFER** or **BYE** depending on the transfer protocol supported by your telephony system. Selecting **BYE** hides the **Transfer number/address** field.|
|Transfer number/address|SIP URI to transfer the call to your telephony system. Use the format `user@domain`. Visible only when **Transfer method** is set to **REFER**.|
