Telecom without the bullshit.
SIP trunking for high-volume call centres and predictive dialers. Ask us what a route costs and an engineer answers with the real number — not a form, not a discovery call, and not a rate card that changes once you sign.

What high-volume dialers actually need
Most carriers treat predictive-dialer traffic as a problem to be priced around. The six things below are where that shows up on your invoice and your connect rate.
No short-duration surcharge
Per-second billing from the first second. No 6/6 rounding, no 30-second minimum, and no surcharge matrix that quietly reprices a campaign of sub-6-second calls.
A-attestation on every INVITE
We sign PASSporTs at our own token authority and hand them straight to Tier-1 networks, so legitimate outbound stops landing as Spam Likely.
Local presence CLI rotation
Outbound caller ID matched to the destination NPA in real time, with rotation that spreads usage across the pool instead of burning one number's reputation.
Burst capacity we will quote you
Edge SBC clusters absorb the 9 a.m. ramp without throttling, dropping packets or answering 503. Ask and we will tell you what your trunk has been tested to — it depends on the route, so a single site-wide number would be a guess.
Real cause codes, in real time
RFC 3326 Reason headers passed through untouched — 486, 487, 503, 603 — streamed into your CDR feed so dialer pacing can react on the same call.
Bare metal, and engineers on the other end
Kamailio proxies and RTPEngine forwarders on dedicated hardware across 12 facilities, so a neighbour's spike is not your jitter. Telegram reaches people who read your PCAP, with no tier-1 script layer first.
Against a legacy wholesale carrier
Reference workload: 100-seat outbound cluster
| Capability | VoIPThug | Legacy carrier |
|---|---|---|
| Short-duration calls | Per-second billing, no surcharge | Rounding rules and surcharge tiers |
| STIR/SHAKEN | A-attestation included | Often B or C, or priced as an add-on |
| Burst capacity | Quoted per route, tested before you sign | Single-digit CPS caps by default |
| Dialer IP provisioning | Whitelisted the same day | Multi-day KYC queue |
| Rates | Asked and answered on Telegram | Quoted after a discovery call |
| Support path | Telegram straight to a SIP engineer | Ticket queue, tier-1 first |
What we sell
Eight things. Ask about any of them and you get the protocol detail, the capacity and the price for your route — rather than a specification sheet written before we knew what you were running.
Call centre SIP trunks
Outbound and inbound for dialers
Built for VICIdial, FreePBX, Asterisk and predictive dialers. Per-second billing and no short-duration surcharge.
DID numbers, 150+ countries
Local, national, toll-free, mobile
Provisioning from carrier-direct inventory, reputation-checked before it reaches your pool, with local-presence rotation.
Wholesale termination
Direct Tier-1 interconnects
Tier-1 termination with least-cost routing, millisecond failover, and no grey routes re-compressing audio that has been coded once already.
STIR/SHAKEN and CLI reputation
Cryptographic identity
Full A-attestation PASSporT signing so legitimate outbound stops arriving flagged as Spam Likely.
Carrier cross-connect
Equinix fibre and public peering
Direct 10G and 100G cross-connects inside Equinix NY4, FR5 and LD8, with peering at DE-CIX, LINX, AMS-IX and IX.br.
SIP API and webhooks
Programmable provisioning
REST and webhook streaming for DID ordering, CDR analytics, balance top-ups and fraud alerts.
Custom SBC architecture
Clustered Kamailio and PBX
Session border controller deployment, Kamailio routing, Asterisk clustering and DDoS-hardened SIP edges, built with your team.
Route audit and dialer tuning
Connect rate and cost
Work through your connect rates, audio faults and carrier invoices with the engineers who run the network.
12 edge SBCs, 4 regions
Cross-connected inside Equinix and peered at DE-CIX, LINX, AMS-IX and IX.br. Voice terminates at the edge nearest the destination, not at a single core.
Land outline: Natural Earth (public domain), equirectangular. Marker positions are the facilities’ true coordinates; the lines show backbone adjacency, not physical cable routes.

Latency depends on your access network and your destination, so we measure it against your traffic rather than publishing an average. Ask for figures on your route.

Get test trunk credentialsTelecom engineers, not a sales floor
We spent a decade inside legacy carriers and their NOCs. We watched providers price around predictive dialers with short-duration surcharges, and take a fortnight to whitelist one dialer IP.
So we built the thing we kept asking those carriers for: VoIPThug — voice infrastructure on our own hardware, priced by the second, provisioned the same day.
There is no tier-1 script layer between you and us. The person answering your Telegram message configures the Kamailio clusters, tunes the Asterisk dialplans and orders the Equinix cross-connects.
