VoIP-GSM GATEWAYS

STANDALONE VoIP-GSM GATEWAY

These gateways are SIP and H.323 compliant. They support all standard protocol feature
and also all available voice related features. The simcards can be set manually with their
working tim e intervall, there is local CDR generation, you can set the codecs, even the
number of voice frames per IP paceket.

VoIP-GSM GATEWAY WITH FULL CAPABILITIES

In this business case the gateways are connected to a Tresto softswitch, so you can
utilize much more features. Why? There are standard protocols like SIP and H.323, but
there has never been a protocol for traffic distribution on simcards, failowering,blacklist,
daily etc. When Tresto VoIP-GSM Gateways are connected to Tresto
SoftSwitches you can streamline the number of features avaiable!

ALL THE FEATURES OF THE BASIC GATEWAY PLUS:

Routing

Sophisticated configurations
Load Balancing
Rerouting
Failowering (multiple levels)
Least Cost Routing
Call routing based on PLMN tariff packadges
Blacklist/Whitelist filtering
RADIUS
Automatic capacity rebalancing
Automatic channel management
Number portability support
Automatic SIM allocation

Sim allocation rules:

Rules can be defined on multiple levels: global, partner, gateway, engine, simpacket, simcard, time
-Static
-will not modify gw settings
-Limits
-sl (day/month)
-packet allowed interwalls
-min/max lines for partner
-Priorities
-sim partnerm, sim, gw
-Desired
-desired minute on packet
-packet multiplier
-Rotate
-minrotateival, desired, maxrotateival
-Price
-min/max pricediff on obj, maxpricepermin for system/partner
-Timetable
-BRS
-LCR
-and many other options
-Daily Minute Limits for SIM cards
-Monthly Minute Limits for SIM cards
-Peak Minute Limits for SIM cards
-OffPeak Minute Limits for SIM cards
-Weekend Minute Limits for SIM cards

Billing

Flexibile pricing
Automatic and Real Time billing (CDR records already includes the prices)
Prepaid and Postpaid platforms

OVERDRIVE GATEWAY WITH SIM ROUTING

All TRESTO gateways are capable of routing SIM cards from all of the gateway's SIM
positions to other gateways, or they can be used without gsm engines as a plain sim server.
This feature is also only available if the gateway is connected to a Tresto SoftSwitch,
as there has never been a standardized protocol for sim routing.
.

ALL THE FEATURES OF THE FULL FEATURED GATEWAY PLUS:

-Automatic predictive estimation and routing of the sim cards.
-All sim cards will use the necessary credit even in case of failure.
-Easier sim management, from only a couple of places
-Absolutely fault tolerant distributed sim server capability

TRESTO SOFTSWITCH

With a SoftSwitch like Tresto's your capabilities will be unlimited. Sim routing, full traffic
engineering, time intervall, priority, sim packet, failower, gateway based routings are
just a few parameters you can set up your routing. Please check the documentation
for more details.
