Qasaar stands for QuesCom Application Server And Advanced Router.

 

Application Server

Appliance running applications
Each application covers a vertical solution (Least Cost Routing, Callback, Mobility, Presence, IVR, Conferencing)

 

Advanced Router

Call router including contextual rules based on route availability, SIM location, price plan and credit as well as on user profile and realtime information (location & presence).

 

A Class 4 Switch
Qasaar gets calls and route them because of application execution. User profile is an important aspect of Qasaar. It can receive calls directly (SIP & H323) and manage remote gateways (QGP & MGCP). Qasaar also manages devices (media gateways & routers).

A PBX
Qasaar won’t implement the PBX features, Qasaar is to be connected to a PBX. A PBX software can run as an application on Qasaar.

 

An Intelligent Network application
Qasaar also supports SIP, QGP, MEGACO protocols

GSM call termination
Efficient call routing to GSM gateways. Calls are routed directly to the correct gateway from SSV information. Simplify switch configuration: Qasaar is the only outbound way for the switch. Avoids tries/retries to find correct gateway. Reduces PDD. Improves failover and load balancing among GSM gateways.

Mobility services
Mobility services are deployed centrally. The appliance can be hosted, “Mobility as a service”=SAAS. Manages PBX, QuesCom gateways & 3rd party gateways. It is build on reliable and scalable database.

Hosted device management (routing, backup…)
Allowing: Centralised provisioning and remote monitoring.

Anti Roaming
User profiles are maintained centrally. Roaming sites can have QuesCom gateway, 3rd gateways or… nothing. Qasaar is provisionning and remotely configuring the phones (mobile phones and fixed phones). Qasaar has global view of network architecture and roaming users.

 

Multisite Enterprise:
Simplify deployment environments. QuesCom gateways are managed by Qasaar (Master/Relay). Rules, routes between gateways and configuration are centralised on Qasaar. CDRs and management is centralised on Qasaar. QuesCom gateways can be low end “passive” products. 3rd party routers can be managed (MGCP/MEGACO).

ISDN cards: it includes an ISDN card, BRI or PRI. Connection to the PBX: it is connected either in pass-through on the ISDN links, or in IP. Grouping: a group of 5 devices can be managed as a unique system.

 

Architectures

Legacy PBX integration

IP integration

 

Seamless LCR for optimum routing

Each call routes according to advanced routing rule to pass it out by the most cost effective network.

 

VoIP migration without changing PBX

For a single site enterprise, QuesCom 400 interconnects VoIP operators in order to make a SIP Trunk. For a multisite enterprise, QuesCom 400 interconnects all sites in IP. The enterprise can smoothly migrate to IP without changing its existing architecture. QuesCom 400 perfectly fits to heterogeneous PBX environments.

 

Failover between voice networks


Because it integrates the ISDN, GSM and VoIP networks, QuesCom 400 allows redundancy in case of failure on one of these networks failure. Routing rules can be configured in order to ensure service continuity. For example, if the ISDN operator access is defective, the equipment can automatically supply a failover link to GSM networks.

A complete SIM card management solution for QuesCom GSM gateways

 

As an addition to your QuesCom GSM gateway solution architecture, the QuesCom SIM Server manages the SIM allocation without the need of human intervention by gathering all SIM cards in a single location. As an addition to your QuesCom GSM gateway, the QuesCom SIM Server takes the best out of GSM providers price plans. According to the time of the day, GSM gateways are loaded with the most adapted SIM cards.

A comprehensive web-based interface enables to manage the SIM allocation based on intuitive rules. No more need to send technical people on site every few days to change SIM cards; all management operations are done from a central site even if your GSM gateways are deployed in several locations or even across countries.

SIM centralization

With the QuesCom SIM management solution, SIM cards are not located in GSM gateways but centralised in one place.
SIM management becomes quick and easy and SIM cards can be stored in a secure place.

 

Flexible SIM

Use as many SIM cards per port as you want without manual intervention and constraint - SIM cards are not anymore permanently attached to a given GSM port.
The QuesCom SIM Server can allocate any SIM on any GSM port according to user-defined rules. It then enables a smooth use of SIM cards across days and months and enables the use of different SIM cards profile during on -peak/off-peak hours.

 

SIM allocation

The SIM server has knowledge of available SIMs in the various SIM arrays. The SIM card to use is selected based on a set of advanced criteria such as current date and time, price plan, GSM provider. Once selected, it provides the gateway with useful information to access this SIM card. The gateway directly contacts the SIM array through TCP/IP to read the SIM information and register it on the GSM network. Periodically, the SIM Server checks GSM port status and then detects when a SIM card needs to be changed. Criteria to change SIMs are a combination of time, date, price plan limit, SIM validity. When one of these criteria matches, the SIM Server will associate another SIM to the gateway. When prepaid cards or monthly plans are running short of credit, SIM cards are automatically removed from routing. A new SIM card is then immediately allocated improving drastically your ASR (Answer Seizure Ratio) and taking full advantage of your GSM gateways.

 

Prepaid management

The SIM Server manages prepaid SIM cards. When SIM credit becomes low, SIM cards get stamped "to be recharged" and parked ready for "top-up".

 

Management and administration

An out-of-the-box web-based interface manages the SIM Server deployment. This interface allows the administration of the SIM cards including advanced features such as SIM array maintenance, and SIM tractability. This web interface has been designed to easily manage large numbers of SIMs. Filtering capabilities combined with SIM status provide a unique SIM tool management interface. In addition, they provide an overall view of all GSM gateways, ASR (Answer Seize Rates) and ACD (Average Call Duration) per gateway, SIM and port.

WHAT DOES IT DO FOR YOU?

 

A QuesCom GSM gateway reduces your telecom bill. Calls from fix phones to mobiles phones usually represent 35% to 55% of a company’s telecom bill. Easy to install, a GSM gateway automatically converts calls from fix phones to mobile phones into calls from mobile to mobile which are cheaper for they are carried through a unique telecom network: the GSM network. The cost of fix to mobile calls on average decreases from 35 to 55%. The gateway offers the enterprise additional features such as fax, SMS or Mobility.

 

 

IS IT REALLY A COST EFFECTIVE SOLUTION?

 

A QuesCom GSM gateway is economically attractive from a monthly rate of 20 hour calls towards mobile phones. Check your phone bill! For instance, a company having 170 hours per month of calls towards mobile phones is charged 1 734 euros. The company can save about 42% on this bill (about 714 euros per month) by installing a QuesCom GSM gateway. In less than 6 months, the investment becomes profitable.

 

DO GSM GATEWAYS REMAIN ATTRACTIVE DESPITE RATE EVOLUTION?

 

A possible reduction of rate “fix to mobile” will not put an end to GSM gateways. Indeed, in most cases, quick return on investment will be preserved by tariff preferences of fleet rates and original price of connection. Not only do QuesCom provide usual functionalities on GSM gateways and so cost reduction benefits, but also solutions such as:

Mobility: mobile phones are integrated within the company’s PBX infrastructure enabling features like sms/fax sending and receiving, mobile extension…

VoIP migration: you can use your gateway to smoothly migrate from an ISDN PBX to a VoIP solution.

IS IT LEGAL ?

 

In all European countries, no law forbids use of GSM gateways within the company’s environment for their own need.

 

WHY IS A QUESCOM GATEWAY A BETTER INVESTMENT THAN A USUAL GSM GATEWAY?

 

The gateway has a unique modularity and makes the investment last longer.
Your usual telecom system is switching to IP?
        The QuesCom gateway “IP Native” is perfectly compatible with former ISDN standard PBX’s and with newest IP-PBX’s.
Your company is growing?
        The gateway’s resources can be upgraded with new hardware add-ons.
Your company is opening a new site?
        By adding a gateway, you can build a multi-site architecture which can be centrally managed.
