Know the economics before you move

Model your migration against published SIP rates before you commit. Lumen's pricing was complex with product-specific models and 12-month terms. Telnyx uses pay-as-you-go pricing with no hidden fees and no contract required. Customers typically save up to 50% switching to Telnyx.

FAQ

You can move the SIP environment you already run without rebuilding it, then modernize on the same carrier infrastructure. That means one migration now instead of another carrier change later when you add programmable voice, real-time media, or Voice AI. We own the network, the APIs, and the portal. Pay-as-you-go pricing with no contract required. 24/7 free support.
