Wholesale voice. Direct from the carrier.

Wholesale VoIP is carrier-to-carrier or carrier-to-reseller voice service at volume pricing. Instead of retail per-user rates, you pay per-minute at wholesale tiers based on monthly volume commitment. SIPNEX provides wholesale voice termination directly from our FCC-licensed carrier network — no intermediary, no markup on markup.

VoIP resellers who sell voice service to end customers, CLECs (Competitive Local Exchange Carriers) needing termination, ITSPs (Internet Telephony Service Providers) building their own voice products, MSPs (Managed Service Providers) bundling voice with IT services, and high-volume call centers where per-minute economics at wholesale rates dramatically reduce costs.

SIPNEX offers volume-based pricing from under 100,000 minutes per month through 10 million+ minutes. Rates decrease as volume increases — from $0.025-$0.030 at the lowest tier to $0.005-$0.008 at the highest. See our pricing page for the current tier structure. Custom pricing available for 10M+ minute commitments.

Yes. SIPNEX supports reseller and white-label arrangements. You purchase wholesale trunk capacity from us and resell to your end customers at your own rates. Your customers see your brand, not ours. We provide the carrier infrastructure. You provide the customer relationship and value-added services.

Yes. A-level STIR/SHAKEN attestation is included on all SIPNEX trunks regardless of volume tier. We sign with our own SP-KI certificate. For resellers: your end customers' calls receive A-level attestation because the signing relationship is between SIPNEX (the carrier) and the verified number authority — not dependent on a reseller intermediary.

SIPNEX provisions DIDs at volume pricing across all US area codes. Bulk orders (hundreds to thousands of DIDs) receive volume discounts. CNAM registration included. Every DID receives A-level STIR/SHAKEN attestation. Provisioning is carrier-direct — same-day for most orders.

For high-volume wholesale customers (1M+ minutes per month), SIPNEX can establish direct SIP peering to reduce latency and improve call quality. Direct peering eliminates intermediate routing hops between your infrastructure and ours.

SIPNEX does not require long-term contracts for wholesale service. Volume pricing is based on actual monthly usage — hit a higher tier and you automatically get the better rate. No minimum term. No early termination penalty. We earn your business every month by delivering quality and value.
