Briefly about the essentials: testing, performance, setup, certificates and warranty.
What does the client get in the end?
A full-featured PBX with all IP-telephony functions at minimal cost: capacity expansion via IP phones, long-distance savings and new services — without replacing the existing station.
How can I try it for free?
There is a free trial program of up to 2 months with no deposit or prepayment — a guarantee letter is enough. We also run online demos.
What is the gateway performance?
Proprietary RtpBridge technology with DSP resources provides up to 30 SIP↔E1 and 30 E1↔E1 connections simultaneously per stream. SIP and PRI signaling is handled by the embedded Asterisk.
What if the solution does not work?
That is exactly why there is a free trial of up to 2 months with no prepayment, plus the MoneyBack program — return within 30 days.
How to make long-distance calls?
SIP trunks are configured via the embedded Asterisk. Integration with popular VoIP operators (Rostelecom, MTT, SIPNET, etc.) is supported.
Who manufactures Alvis gateways?
GarantPlus Ltd — a Russian developer and manufacturer, Yaroslavl. On the market since 2000.
Do you help with setup?
Yes, GarantPlus performs basic configuration for free. Priority support is available for VIP clients.
How secure is it?
The Rescue-4E1 module provides failover on outage. On the SIP side, protection mechanisms are applied (iptables, fail2ban).
Is there an SSS certificate?
Yes, the Alvis line is SSS-certified and has an EAEU TR declaration of conformity. See the Certificates page.
What is the warranty?
5 years factory warranty, extendable by another 5 years, plus the MoneyBack program.
