Lumen is exiting voice. Move before your timeline stops being yours.
Move your SIP trunks and numbers without rebuilding your voice stack. Keep SIP today, then add programmable voice, real-time media, and Voice AI when you are ready. Pay-as-you-go pricing. No contract lock-in. A platform that's investing in voice, not shutting it down.
Licensed global carrier with native SIP trunking on a private IP network. Direct PSTN connectivity, no reseller markup. Local numbers in 130+ countries, all on owned infrastructure.
Lumen is moving enterprise voice toward end-of-sale as investment shifts to other strategic areas. No new sales or renewals since August 1, 2026.
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.
