This comprehensive guide outlines the setup of a secure Transport Layer Security (TLS) connection between Vodia and Telnyx, emphasizing the crucial aspects of data confidentiality and integrity. By following the steps provided, users can establish a secure SIP trunk connection. This TLS connection guarantees encrypted and secure communication, enhancing data protection and privacy for your business.
In this blog we guide you through the process of setting up a TLS connection between Vodia and Telnyx. TLS provides secure communication over the Internet, ensuring the confidentiality and integrity of data exchanged between the two systems; by following the stops below, you can establish a secure connection for your SIP trunk.
Connecting with Telnyx
Create a SIP registration connection in Telnyx.
Step 1: Connecting with Telnyx
Create a SIP registration connection in Telnyx.
Choose "Registration" as the type, then copy your SIP password.
The SIP password will be required when setting up the SIP trunk on the Vodia phone system.
Save and finish the registration.
Edit the connection and enable Secure Real-Time Transport Protocol (SRTP) under "Encrypted Media".
Save the configuration.
Note: Outbound settings already utilize SRTP settings from the inbound settings.
Step 2: Configuring the Vodia Phone System
Navigate to the SIP trunk to create your Telnyx connection in the Vodia phone system.
Click on "Add" and select "Telnyx."
Enter your Telnyx SIP account details: • Name: Provide a name for your trunk. • Password: Enter your Telnyx SIP credentials. • User: Enter your Telnyx user account. • DID: If applicable, enter your Direct Inward Dialing (DID) number. • Save the configuration.
Configure TLS under "Proxy Address" by using the following example: Proxy Address: sip:sip.telnyx.com;transport=tls
Navigate to the SIP trunk to create your Telnyx connection: Click on “Add” and select "Telnyx."
Configure the TLS under "Proxy Address" by using the following example:
Proxy Address: sip:sip.telnyx.com;transport=tls
Step 3: Caller ID and Phone Numbers
To define the Caller ID used when making calls from the Vodia system, follow these steps:
Define the FROM headers and Remote Party ID under the SIP caller-ID presentation: • Choose "custom headers" from your Telnyx SIP trunk. • You can set up the Domain ANI in the Tenant general settings under "dom_settings.htm". • Alternatively, you can set up an ANI on the extension and instruct the header to use "Extension ANI".
By following the above steps, you can establish a TLS connection between Vodia and Telnyx, ensuring secure and encrypted communication for your SIP trunk; this added layer of security helps protect your data and ensures the privacy of your calls. Implementing TLS is a crucial step in maintaining a secure communication infrastructure for your business.
Every business handles calls differently, and its phone system should support those differences. Vodia PBX gives businesses and service providers the flexibility to shape call flows, configure individual tenants and extensions, and build a branded experience for their customers. Queues, ring groups, schedules, forwarding, and AI agents can work together around each team’s requirements, while the REST API connects the phone system with wider business workflows.
Vodia PBX now supports xAI’s Grok, giving partners another option for building AI voice agents for their customers. Using Grok’s speech-to-speech API, a Vodia Voice Agent can greet callers, ask who they’d like to speak with and transfer them to the appropriate extension. For example, a caller can simply say they’d like to speak with sales and be connected to the sales team. The article walks through what you need to connect Vodia PBX to Grok and includes a sample call transfer script you can adapt to your own call flow.
Vodia PBX 70.7 brings practical improvements to hotel operations, call quality troubleshooting, outbound dialing, and device provisioning. A new Hotel Front Desk template puts room status, wake-up calls, and guest services in one place, while additional call quality metrics help teams investigate audio issues. Updates to the User Web Portal, reporting schedules, hardware support, and integrations give MSPs, resellers, and service providers more tools to manage deployments and support their customers’ everyday communications.
