Talk to an Operator.

SIPNEX is an FCC-licensed carrier with its own operating authority — not a reseller, not a white-labeled trunk from another provider. We hold our own STIR/SHAKEN Service Provider certificate, which means every outbound call is signed at A-level attestation directly on our network. No intermediary signing. No downstream attestation downgrades.

Our support team consists of engineers who configure VICIdial and high-volume dialers on our own infrastructure. When you call with a question about sip.conf, codec negotiation, or CID rotation strategy, you speak with someone who has solved the same problem on their own production system. Average ticket response time is under two hours during business hours.

We operate on a no-contract, transparent pricing model. Per-minute rates are published on our pricing page — no quote gates, no volume commitments required to get started, and no early termination penalties. You scale up or down based on your campaign needs.

From trunk provisioning (typically within 24 hours) to ongoing compliance support including STIR/SHAKEN certification and TCPA compliance tooling, SIPNEX provides the carrier infrastructure that high-volume outbound operations depend on.

Messages submitted through this form land in the same inbox monitored by our engineering and carrier operations teams. There is no outsourced call center, no offshore tier-1 filter, and no chatbot rewriting your question before a human reads it. When you describe your setup — for example, "VICIdial on Asterisk 18, 200 concurrent channels, nationwide outbound with aggressive local-presence CID rotation" — the first person to reply will already understand what every phrase in that sentence means.

SIPNEX holds direct FCC operating authority, is a registered Form 499 contributor to the Universal Service Fund, operates its own STIR/SHAKEN Service Provider certificate (issued by an FCC-approved Certification Authority), and maintains a current registration in the Robocall Mitigation Database. These credentials are visible on every call we sign. For dialers, CCaaS platforms, and enterprise outbound operations evaluating carriers on regulatory posture, these are the trust signals that matter — and the ones we are happy to discuss in detail when you reach out.

Typical response times during business hours: under two hours for new sales inquiries, under thirty minutes for existing-customer technical issues, and same-day for porting, LOA processing, and RespOrg coordination. Outside business hours, genuine service-affecting incidents route to the on-call engineer via our NOC pager. For anything else, a reply the next business morning is the default.

If this is your first conversation with a carrier rather than a reseller, we can also walk you through what changes operationally: direct trunk registration, A-level attestation by default, number portability without third-party LOAs, CDR access on request, and the ability to make routing changes without opening a ticket with an upstream wholesaler. That conversation usually takes fifteen minutes. We are happy to have it.
