Call Forwarding Setup

This simple yet effective method allows you to quickly redirect your calls to our voice agents.

Dedicated Number — Volubile provides you with a unique number dedicated to your organization
Redirection Setup — You configure your existing phone systems to forward incoming calls to this number
Automated Handling — Our AI voice agents handle all redirected calls according to the configured scenarios

This option may incur additional costs associated with call forwarding from your phone infrastructure. These fees vary depending on your current phone provider.

SIP Trunking Setup

This feature is not available for all accounts. To enable it, contact your Customer Success Manager (CSM).

This advanced method offers deeper integration and optimal performance for professional environments.

Prerequisites — Ensure that the “SIP Trunk” feature is enabled on your Volubile account
Connection Settings — Access the SIP credentials in the administration interface:

Settings > SIP > SIP Trunk

You can configure an authentication method:

IP Address Authentication

Enter the IP addresses allowed to connect to the SIP trunk
You can use CIDR notation to specify address ranges
Example: 203.0.113.1 or 203.0.113.0/24

Credential Authentication

Username: 5 to 32 characters (letters, numbers, hyphens only)
Password: 12 to 64 characters (must contain at least 1 digit, 1 lowercase letter, and 1 uppercase letter)
Case-sensitive

Connection Information:

In the telephony configuration section of your agent, you will find the essential information to establish the connection with your phone infrastructure.

The following parameters are required for configuring your SIP connection:

SIP Server Address: The FQDN of our SIP server that your system must connect to Example: volubile-efe2e38.sip-eu.vonage.com
Agent FQDN Identifier: The unique identifier used to authenticate your agent upon connection Example: 5389079

Client Configuration — In your phone infrastructure:

Configure the authentication on the SIP trunk according to the chosen method (IP or credentials)
Set up the forwarding of incoming calls to our SIP server

SIP headers options

From header

If the caller’s number is not correctly transcribed in the platform, it is possible to send it through the SIP header X-Volubile-System-From during call setup. This method allows for seamless integration with your existing systems.

Example

X-Volubile-System-From = +33612345678

To header

If the recipient agent’s number cannot be overridden by your telephony system, as in the case of SIP redirect, you can use the SIP header X-Volubile-System-To to specify the Volubile agent’s number.

Example

X-Volubile-System-To = 2566458
