GTAS Global Telephony Application Server
|
Summary
GTAS is a hardware-independent telephony application server offered by GET Group to provide CTI (Computer Telephony Integration ) developers and telephony operators with a connection monitoring system and .NET telephony service development package (SDP).
Using SDP,developers can build connection protocols and hardware-independent telephony services such as IVRs, call centers, PBX’s, fax pools, VoIP, SS7 services, etc… Operators can deploy those services into GTAS using its service loader to provide reliable and controllable telephony services.
Being a multithreaded application server, GTAS is capable to manage and control thousands of instantaneous telephony connections by dedicating multiple services to handle different calls.
GTAS services are developed and deployed as front-end solution. Neither the service nor the developer cares about the connection type or telephony hardware used.
GTAS provides configuration tools to manage and control telephony boards and connections. It also provides some add-Ins applications for service testing and deployment.
Features
GTAS is a global telephony application server that provides a dynamic mechanism to manage telephony media resources. With a very friendly user interface, GTAS enables users to configure installed telephony boards, manage telephony connections, and have full controls on connection channels. GTAS operates telephony processing media providing protocol and connection type independent interfaces to build, load and run telephony applications.
-
GTAS Main Frame
GTAS starts by detecting media processing and signaling boards on the host. Then, it arranges boards in multiple panels. Board panels provide the following features:
-
Monitoring Systems
GTAS monitoring system enables an application to:
-
Monitor alarms on T1 and E1 trunks
-
Retrieve trunk state information on BRI trunks
-
Gather performance statistics
-
Easily detect digital trunk failures
-
Trunk Control Programs
Trunk control programs perform all signaling tasks necessary to interface with the telephony protocol used on the line or trunk. TCPs are loaded by GTAS into the media board during initialization

-
Digital Signal Processors
Each board has a high-performance digital signal processor (DSPs) that provides resources for call processing and programmable voice processing
-
Communication Channels
GTAS enables users to have a full control on the media resources while the channel is connected. It provides descriptive and helpful controls to manage media resources by modifying and changing their default value.

Telephony Service Loader
The SDP enables developers to design and build customized telephony services such as IVRs, PBXs, fax pools, announcement broadcasters, etc… GTAS can run and operate multiple GTAS telephony services concurrently. The services can be loaded into GTAS by adding a service and providing its name, number, and location in the host. GTAS service loader validates the service before loading it into GTAS.
-
Outgoing Calls Tester
GTAS users are able to place outgoing phone calls and to transmit DTMF and FSK strings over connected channels. GTAS provides users with phone pad simulator to place real outgoing phone calls and interact with called parties. Developers can also use this phone pad simulator to test their services after loading it into GTAS.
Benefits
GTAS is an application server that provides a mechanism to easily build, deploy and run telephony services. Telephony services are developed as .NET class libraries using a service development package (SDP) deployed with GTAS.
-
IVR Services
Enterprises are increasingly turning to IVR to reduce the cost of common sales, service, collections, inquiry and support calls to and from their company.
Basically, IVR solutions have used pre-recorded voice prompts and menus to present information and options to callers, and touch-tone telephone keypad entry to gather responses. Modern IVR solutions also enable input and responses to be gathered via spoken words with voice recognition.
-
Voice Conference Services
Voice conference service (VCS) allows callers to create virtual meeting rooms in which several participants can converse with one another simultaneously. GTAS conference service provides the following capabilities to participants:
-
FAX Pool Services
Fax pool services can be implemented to transmit and receive Group 3 facsimiles at rates of up to 14,400. Fax pools can offer services for LAN fax, fax broadcast, fax-on-demand, store-and-forward, and real-time fax-over-IP data networks. Fax servers must support the following features:
-
Enhanced Group 3 fax features
-
The T.37 format, specified as 1D encoding, low resolution, and A4 page-width
-
The ability to convert documents into different formats, resolutions, or encodings online (on-the-fly) or offline
-
The ability to poll a remote fax terminal and request that it transmit a fax
-
PBX Services
PBX stands for Private Branch Exchange. It is a PSTN or IP telephone network used within a private enterprise. Users inside a PBX share outside lines which they use to make phone calls external to the PBX. Companies use a PBX for connecting all their internal phones to the external line(s). This way, they can lease only one line and have many people using it, with each one having a phone at the desk with different number. A PBX reduces cost because the company only pays for the number of lines liable to be connected at any given time to the outside. If a company has 250 offices, it's unlikely everyone will be making an outside call at once. Perhaps only 10% will require an outside line at any given time. Therefore the company can lease an E1 (31 channels) or T1 (23 channels) line from the phone company rather than 250 phone lines!
-
Call Center Services
A call center is a centralized office used for the purpose of receiving and transmitting a large volume of requests by telephone.
A call centre is operated by a company to administer incoming product support or information inquiries from consumers. Outgoing calls for telemarketing, clientele, and debt collection are also made. In addition to a call centre, collective handling of letters, faxes, and e-mails at one location is known as a contact centre.
