Key Telephone System A key telephone system enables a user to use DSS keys for accessing Stations or trunk keys by simply pushing a button or “key” on a telephone. The KTS phone is multi-functional, user friendly and multi-key instrument. Hold and intercom buttons are typically used to place a call on hold so that the call can be “announced” over the intercom line before being distributed to the person for whom the call is intended. Most business key telephone systems are “squared,” which means that every telephone has the same number of buttons or line appearances. This concept works especially well in small offices, where anyone can retrieve any CO line from any telephone in the system. Key telephone systems also simplify how users can establish conference calls, since all active lines appear on all telephones. The KTS systems with applications can cater to various segments as follows:

Hotels with Basic Hotel Motel features
Domestic call centers with ACD MIS
Residential Users
SOHO like travel agencies
Financial segments with dealing room and logging solutions.
Banking segment with multiple branch offices

PBX /Hybrid IP Telephone System A PBX telephone system, or Private Branch eXchange, requires that a user first dials a code — usually “9” or “8” — to access an outgoing facility such as a CO trunk, Tie trunk, ISDN PRI, BRI channel. Telephones do not require dedicated buttons for Hold and Intercom, although these conveniences can be provided as options. PBX systems typically satisfy business requirements ranging from a few trunks and stations to many thousands of trunks and stations — far more than the amount key telephone systems can support. Multiple-location support and networking are also characteristics of PBX systems. Unlike a key telephone system, a feature such as conferencing can require a user to dial a feature access code to add on conference participants. Most up-to-date PBX systems also offer the option of using telephones with pre-programmed buttons to invoke feature access. Hybrid IP systems also provide packet switching and support IP extensions and IP trunks with addition of hardware and software. The main technology is PCM/TDM and IP depending on the switch. The Hybrid PBX systems with applications can cater to various segments as follows :

Hotels with Advanced Hotel and PMS applications
International call centers with CTI applications
VOIP with peer-to-peer communications and IP networking
Corporate Houses with various business features
Enterprise Networking with various branch offices.

IP Systems IP systems are mostly based on server/client and come in form factor of ‘n’U size rack mountable which is more appealing to the IT staff. They provide primarily IP extensions. For Analog Extensions and PSTN connectivity, IP servers provide media gateways and media converters. The main technology is packet-switching, and they work on data infrastructure. QOS, Jitter and delay handling are the main issues here. The IP systems with applications can cater to various segments as follows:

Converged voice and data solutions
CTI and Voice logger Solutions based on IP Platform
Multi-office networking on IP and remote survivability
Other applications in the PBX category

Unified communications Solutions Unified communications (UC) is “an industry term used to describe all forms of call and multimedia/cross-media message-management functions controlled by an individual user for both business and social purposes”. This potentially includes the integration of fixed and mobile voice, e-mail, instant messaging, desktop and advanced business applications, Internet Protocol (IP)-PBX, voice over IP (VoIP), presence, voice-mail, fax, audio video and web conferencing, unified messaging, unified voicemail, and white boarding into a single environment offering the user a more complete but simpler and more effective experience. Unlike Unified Communication which refers to a real time delivery of communications based on a preferred method and location of the recipient, Unified Messaging Systems culls messages from several sources, such as, e-mail, Voice Mail, and faxes, but holds those messages for retrieval at a later time.
