How it works

Signaling control at the E1/SS7 junction

Hover a node — we explain what it does. The dots show calls and checks passing through.

GARANT PLUS — on the register of Antifraud-system developers

GARANT PLUS is on the official register of Antifraud-system solution developers. GarantPlus has been known on the E1-gateway market since 2009, when it introduced the Alvis-GW-2E1 gateway. Since 2013 we hold SSS declarations for our equipment and fully honour our 5-year technical-support commitments.

We adapted the Alvis E1 gateways for use within the UVR (resource-interaction unit) of the Antifraud system and completed successful integrations with many UVR vendors on the market. The current register of Antifraud-system solution vendors is available in the Telecom Operator Personal Account on the GRChTs website.

* GARANT PLUS does not impose a particular UVR, leaving the choice entirely to the Customer, and enables migration to another UVR without repeat payment. We look forward to new integrations!

UVR “GRIFIN” — cloud solution

UVR “GRIFIN” is arguably the most widespread cloud antifraud solution on the market. Its advantages include fast integration, fully automated management (uploading number capacity, etc.), a fairly convenient HTTP API, quick implementation of new GRChTs and Garda requirements, support for the “C-number”, and much more.

GarantPlus fully supports out-of-the-box connection to this UVR over HTTP API, including automatic switching between GRIFIN servers and availability checks.

UVR “TELESTOR” — cloud solution

The advantages of this solution are fast integration, excellent client support from project start to finish, integration of various technical solutions for connecting to the PBX (including our gateways), superb technical support and staff competence.

GARANT PLUS fully supports out-of-the-box connection to this UVR over SIP Rerouting API, including setting direction tags and other interaction parameters. Read more about connecting to UVR “TELESTOR” in our Alvis Wiki article.

UVR “TIXEN” — on-premise solution

UVR “TIXEN” is a fully on-premise UVR, independent of cloud solutions. Its advantage is a boxed distribution for complete UVR deployment without installing separate components. TIXEN specialists provide full technical support.

GarantPlus fully supports out-of-the-box connection to this UVR over HTTP API (connections over the local network). Read more about connecting to UVR “TIXEN” in our Alvis Wiki article.

Three E1 connection modes

1 · In-line on the E1 stream. SS7 (ISUP) or EDSS1 PRI. Suitable for most PBXs without any reprogramming.

2 · “Rerouting” mode. Usually EDSS1 PRI. Achieves the highest gateway utilisation without touching the physical layer of the external E1 streams. Supported by some PBXs: Almaz (Proton SSS), M-200 (MTA) and some others.

3 · “Loop” mode. Usually EDSS1 PRI. If the load per uplink on the PBX is not that high, traffic from several streams can be routed through one or several gateways connected to the free ports of the PBX.

  • A domestic manufacturer with 15 years of experience developing and producing E1 gateways; our products hold SSS declarations, and we are preparing to enter the TORP register.
  • Priority-support packages are available — you will never hear “read the pinned posts” from us. We are ready to help customers even in seemingly hopeless situations.
  • Smooth migration from one UVR to another with no need to buy additional equipment. Users often want to move from a cloud UVR to an on-premise one over time — we can help with that.
  • We integrate both over HTTP API and over SIP with most UVRs on the market. We are ready for new custom integrations where the Customer has specialised solutions.
  • Our specialists have extensive experience connecting to various PBXs and have already completed dozens of successful Antifraud-system deployments.
