The SIP Carrier
VICIdial Was Waiting For.

The only VICIdial carrier that actually holds its own FCC license, its own 499 filer ID, and signs your calls with its own STIR/SHAKEN certificate. No resellers. No rewrapped trunks. Just operators who run dialers selling to operators who run dialers.

THE DIALER OPERATOR'S MONDAY

Your generic carrier doesn't know what you do.

They sold you a trunk designed for an office phone. You're running a call center. The misfit shows up every day — in call drops, flagged CIDs, B-level attestation, and a support queue that doesn't understand what "VICIdial" means.

Your CIDs keep getting flagged

Without direct A-level attestation from the originating carrier, your numbers degrade fast. Most resellers can only hand you B-level.

Your answer rate collapsed overnight

Carriers change STIR policy and don't tell you. You find out when your dashboard drops 30%.

Your carrier doesn't know VICIdial

Support tickets that start with 'what's sip.conf' are a sign you're not with the right partner.

OPERATOR-OWNED

We run dialers. So we built the carrier we wished existed.

SIPNEX isn't a CPaaS wrapper. Isn't a Twilio reseller. Isn't a marketing-first "communications platform" run by engineers who've never burned a CID on a Monday morning.

We're an FCC-licensed carrier that owns its own STIR/SHAKEN SP certificate. Every call we originate, we sign — directly. That means A-level attestation without downstream dilution, and a support team that speaks VICIdial fluently because we dial on our own network.

FREQUENTLY ASKED

Operator-to-operator answers.

What is a VICIdial carrier?
A VICIdial carrier is a SIP trunk provider whose platform is specifically tuned for VICIdial's predictive dialing behavior: high concurrent channels, fast call setup, flexible CID handling, and A-level STIR/SHAKEN attestation. SIPNEX is operator-owned — we run VICIdial on our own network and sell the carrier service to other operators.
Why does my dialer need a specific carrier?
Generic carriers throttle high-velocity outbound traffic, apply B-level attestation, and have support teams that don't understand predictive dialing. VICIdial operators need unlimited channels, direct A-level signing, CID rotation flexibility, and engineers who speak sip.conf.
Can SIPNEX handle 1,000+ concurrent calls on one VICIdial instance?
Yes. Our carrier infrastructure is built for high-concurrency outbound. Channel capacity is not capped at the trunk level — you scale as your instance scales.
How do you prevent CID burn on high-velocity campaigns?
Two things matter: (1) direct A-level STIR/SHAKEN attestation from the originating carrier, which we sign ourselves with our own SP-KI certificate, and (2) intelligent CID pool management integrated with VICIdial's dialer logic. We help operators configure both.
Do you provide STIR/SHAKEN A-level attestation for VICIdial outbound?
Yes. SIPNEX holds its own STIR/SHAKEN Service Provider certificate, meaning every outbound call signed at our network is attested at the A level — not reshipped through a downstream carrier that can only provide B or C level.
How fast can I be dialing with a new SIPNEX trunk?
24 hours is typical from signed agreement to live trunk. Complex porting scenarios take longer but we provision your initial DIDs and trunk credentials within one business day.
What's the difference between SIPNEX and Bandwidth or Telnyx for VICIdial?
Bandwidth and Telnyx are excellent CPaaS carriers but are built generic-first — their support teams and tooling aren't VICIdial-specialized. SIPNEX is operator-owned and VICIdial-native, meaning every decision we make (CID tooling, channel limits, support response, pricing structure) is optimized for dialer operators.
Are you TCPA compliant?
SIPNEX provides the carrier infrastructure and compliance tooling (attestation, call recording controls, opt-out signaling) that supports TCPA-compliant outbound. The legal TCPA obligations — consent capture, DNC scrubbing, time-of-day rules — remain with the caller. We give you the tools; we don't take the responsibility off your plate.

Talk to an operator.
Not a rep.

Tell us how many instances you're running and how many minutes you dial a month. We'll tell you whether SIPNEX is the right fit — honestly.
