VAPI SIP Trunk
The demand for real-time, human-like AI conversations is exploding, and VAPI (Voice AI Platform Interface) is at the forefront, enabling developers to build incredibly responsive AI agents. But a powerful AI needs an equally powerful connection to the outside world. This is where "Bring Your Own" (BYO) SIP Trunking comes in, and Aancall LLC is leading the charge as the preferred partner for VAPI users seeking a robust, cost-effective, and globally capable alternative to traditional providers.
If you’re building with VAPI and want to ensure crystal-clear audio, low latency, and global reach without breaking the bank, look no further than Aancall's Platinum SIP Routes.
Why Your VAPI AI Needs a High-Performance BYO SIP Trunk
VAPI is designed to be carrier-agnostic, allowing developers to connect to high-performance SIP trunks. Choosing Aancall as your BYO partner offers advantages that standard, all-in-one platforms cannot match:
Wholesale Economics: As your call volume grows, Aancall’s competitive rates ensure your margins remain healthy.
Global Reach: Instantly access local numbers (DIDs) in 60+ countries, giving your AI a local presence in markets like the UK, UAE, Australia, and beyond.
Platinum Route Reliability: AI requires low latency and high-fidelity audio for accurate Speech-to-Text (STT). Our Platinum routes prioritize traffic for maximum clarity.
Aancall Seamless Technical Integration with VAPI
VAPI supports a variety of connection methods. Aancall is engineered to support all of VAPI’s primary "BYO" configurations:
1. SIP Domain & Credential Authentication
Similar to providers like Zadarma, Aancall allows you to connect using standard SIP credentials.
SIP Server:
Use Aancall's SIP serverAuthentication: Simply provide your Aancall username and password within the VAPI dashboard.
No Registration Needed: VAPI does not require a SIP
REGISTERhandshake, and Aancall is optimized for this "Invite-only" flow, reducing latency.
2. IP-Based Authentication & SIP Gateways
For enterprise-level security and speed, Aancall supports IP-based authentication, mirroring the workflows of providers like Plivo or Telnyx.
Secure Handshake: Whitelist VAPI’s signaling IPs in the Aancall portal for instant, password-less authentication.
SIP Gateway: Route traffic through a dedicated Aancall SIP domain to ensure your traffic hits the closest geographic POP (Point of Presence).
How to Configure Aancall with VAPI
Setting up your Aancall BYO SIP Trunk is a straightforward process:
Step 1: Provision Your Global Number
Log in to the Aancall Portal and select your international number. Ensure the number is active and configured for SIP traffic.
Step 2: Set Up the VAPI Credential
In your VAPI Dashboard:
Navigate to Telephony > Import Number.
Choose the BYO SIP Trunk option.
Enter your Aancall SIP Domain and credentials (or IP whitelist).
Format: Ensure your phone numbers are in E.164 format (e.g.,
+1234567890).
Step 3: Configure Inbound/Outbound
Inbound: Route calls from your Aancall DID to VAPI’s unique SIP URI provided in your dashboard.
Outbound: Assign your Aancall credential as the default carrier for your AI agent’s outbound calls.
