Frequently Asked Questions
What phone numbers can I use for my AI voice agents?
DIDWW provides local, national, mobile, and toll-free DID numbers across 90+ countries and 5,600+ area codes. Local DID numbers are the most common choice for AI voice agents - they give your agents a local caller ID matched to the region they're calling in, which improves answer rates. Numbers are provisioned instantly via the self-service portal or REST API.
Does DIDWW support BYOC for AI voice platforms?
Yes. DIDWW works as a BYOC carrier for any SIP-compatible AI voice platform. Bring your DIDWW phone numbers and SIP trunking to the platform your business already uses - including ElevenLabs, Retell, and Vapi - without switching platforms or rebuilding your setup. Full BYOC documentation is available at DIDWW documentation.
Can my AI agent make and receive calls on the same number?
Yes. DIDWW provides two-way SIP trunking for inbound and outbound calling on the same DID number. Your AI agent can receive inbound calls, make outbound calls, and send and receive SMS, all from one number managed in a single DIDWW account.
Why use a dedicated carrier for AI calling instead of numbers from my AI provider?
AI platforms that include phone numbers act as resellers - you pay a markup and the numbers are tied to their platform. DIDWW is a licensed carrier in 30 countries with own numbering resources in 19. Your DID numbers live in your account, port freely, and connect to any SIP-compatible AI platform.
Does call quality at the carrier level affect my AI voice agent performance?
Yes, audio quality at the carrier layer directly affects speech-to-text accuracy. Poor audio means more transcription errors and worse AI output. DIDWW operates a geo-redundant private network with 99.998% uptime, direct peering, and no third-party resellers in the carrier path, delivering the clean audio AI voice agents need to perform consistently.
Can my AI agent provision its own phone numbers through MCP?
Yes. DIDWW MCP lets compatible AI clients connect to your DIDWW account and use natural-language requests to search coverage, check pricing, purchase phone numbers, configure inbound routing, manage capacity, and perform other supported account tasks. Your existing DIDWW account permissions still apply, and purchases and other protected actions require confirmation before they are completed.
