Voice AI: Cut Telecom Costs with an Exchange, Not Direct Deals

In the growing competition landscape of Voice AI, rapid global expansion and flawless performance are key. Establishing direct relationships with telecom carriers might seem like a straightforward path to sourcing SIP trunks. It helps in ensuring connectivity. But, it often hides a labyrinth of unexpected costs and operational headaches. For Voice AI companies focused on innovation and growth, these hidden burdens can significantly impact your bottom line and agility.

It’s time to look beyond the surface. We need to understand the true cost of direct carrier deals. A modern telecom exchange like NeuTRAFIX offers a smarter, more cost-effective solution, here is why.

The Iceberg Effect: Uncovering the Hidden Costs of Direct Carrier Relationships

The advertised rate from a direct carrier is just the tip of the iceberg. Beneath the surface lie numerous costs that can inflate your telecom spend and drain valuable resources:

• Lengthy Negotiation & Legal Overheads: Each direct carrier deal requires extensive negotiation, contract reviews, and legal fees. Multiplying this across several countries creates a significant time and monetary sink.
• Steep Minimum Volume Commitments: Many carriers impose high minimum volume commitments. If your Voice AI application’s usage fluctuates, you could be paying for capacity you don’t use. The same is true if it’s still growing in a new market.
• Lack of True Rate Transparency: Without a centralized marketplace, how do you know if you’re truly getting competitive rates? Benchmarking across multiple individual carriers is a complex, ongoing task.
• Complex Integration & Ongoing Maintenance: Each carrier may have its own API, platform, and technical nuances. Integrating and maintaining these disparate systems demands significant engineering resources.
• Multiple Invoices & Currency Headaches: Managing invoices from numerous carriers in different currencies adds administrative complexity. It also introduces potential currency conversion losses.
• Time-to-Market Delays: The lengthy procurement and setup process for each new carrier takes time. It can delay your entry into new markets. This delay costs you valuable opportunities.

Use Case: Voice AI Assistant Expanding Globally

Imagine your Voice AI assistant is gaining traction and needs to support users in five new countries.

Are You Ready to Optimize Your Telecom Spend?

Ask yourself these questions:

• How much time does your team spend managing carrier relationships?
• Are you confident you’re getting the best possible rates in every market?
• Do telecom complexities slow down your global expansion plans?

If these questions resonate, it’s time to explore a more efficient model.

Integrating Vapi with a Telecom Exchange Powered Platform (e.g., NeuTRAFIX) via Custom “BYO” SIP Trunk

Use Vapi’s “Custom ‘BYO’ SIP Trunk” feature for connection. It connects with your chosen telecom exchange platform like Neutrafix. You can also use others powered by TelecomsXChange technology. This integration unlocks global carrier access, competitive rates, and enhanced routing capabilities for your Voice AI agents.

Here’s a concise guide to get you started:

1. Coordinate with Your Telecom Exchange Platform Provider:

• IP Allow listing (Essential): Your exchange platform provider must allowlist Vapi’s dedicated SIP IPs: 44.229.228.186/32 and 44.238.177.138/32.
• Obtain Connection Details: From your exchange platform provider, get your:
  • SIP gateway address(es).
  • Phone number(s) (DIDs) intended for Vapi.
  • Authentication credentials. Vapi generally recommends SIP registration with username and password for BYO trunks. This is unless your provider offers unique termination URIs. These are suitable for IP-based authentication from Vapi’s shared IPs.

2. Configure Vapi (via Vapi API):

• Create SIP Trunk Credential: Use Vapi’s API (POST /credential) to establish a byo-sip-trunk credential. Input the gateway and authentication details received from your exchange platform. Make sure to save the Credential ID provided in the API response. (For the exact JSON payload, please refer to the Vapi API documentation.)
• Link Your Phone Number: Utilize Vapi’s API (POST /phone-number). Use it to associate your DID, obtained from your exchange platform, with the Credential ID created in the previous step. Note the Phone Number ID from the response.

3. Finalize Routing & Conduct Thorough Testing:

• Inbound Call Routing to Vapi: Crucially, your exchange platform must be configured to route inbound calls for your DID to Vapi’s specific SIP URI (typically formatted as {phoneNumber}@<credential_id>.sip.vapi.ai). Confirm this setup with your exchange platform provider.
• Comprehensive Testing:
  • Initiate outbound calls from Vapi through the exchange platform to ensure correct routing and audio quality.
  • Make inbound calls to your DID to verify they reach your Vapi AI agent as expected.
• (Optional) Call Transfer (SIP REFER): If needed, configure SIP REFER requests. Direct them towards your exchange platform’s SIP domain. Ensure this is done according to their specifications.

Key Advantages of This Integration:

Connecting Vapi to a TCXC-powered exchange platform offers direct access to a global carrier marketplace. It provides competitive pricing and advanced call management features. This connection maintains your core AI logic within Vapi. This creates a powerful and scalable solution for your Voice AI services.
