Modules that talk to each other — from the call engine to whitelabel panels. The core serves voice carriers in any country; a separate set covers Brazil's regulatory compliance.
The call engine: routes, interconnections and numbering that work for any carrier, in any country.
Least Cost Routing: every call through the lowest-cost route, automatically.
Routing rules by prefix, supplier and time, with failover between trunks.
Rewriting of origin (A) and destination (B) numbers via regex, before and after routing.
SIP and SIP-i trunks and interconnections with suppliers and other carriers.
Several SIP connections on the same circuit (SIP account), with independent channels and billing.
Unlimited registration of numbers (DID) across countries, with follow-me and per-number blocking.
Voice quality, protection and availability to sustain the operation at scale.
Broad support for audio codecs (Opus, G.729, G.711…) and video, with SRTP and TLS.
An edge layer for security and balancing, protecting the core of the operation.
Blocking by IP and UDP/SIP ports against scanning, flooding and fraud attempts.
Identity attestation against spoofing and phantom calls — included at no cost.
Redundant servers in HA, balancing, real-time synchronization and daily backups.
From thousands of simultaneous calls to unlimited channels, with no licensing fees.
Management, whitelabel resale, billing and API to commercialize voice under your brand.
The main administration panel: customers, circuits, plans, routes and reports in one place.
A whitelabel portal for the reseller to manage their own customers, plans and billing.
A whitelabel portal for the end customer to view invoices, usage and call details.
Controlled, prepaid and postpaid — with a daily spending limit per circuit.
Detailed real-time call records for rating, auditing and reconciliation.
ASR/ACD, profitability, channel occupancy and dozens of reports to decide with data.
REST API to provision accounts, query CDRs and invoices and integrate your systems.
Specific modules for Brazilian STFC carriers, aligned with Anatel rules.
Traffic Declaration Document for traffic reconciliation and billing between carriers.
Management of the Carrier Database (BDO) and the traffic carried on your network.
The Saper Portability System integrated with the SOA, to port numbers securely.
Unlimited channels and traffic, with no licensing fee. You grow by adding Communication Servers — without changing platforms.
With RTP, media flows through the server — each call costs more, so capacity is lower. Without RTP (media direct between endpoints), the same hardware sustains far more calls. Conservative estimates — actual capacity varies with the hardware. View the technical datasheet →
Every operation is different. In a quick conversation, Saper points out exactly which servers you need today — and what can wait for later.
