SERVER BASED IP COMMUNICATION PLATFORM

IPG COMMUNICATION PLATFORM CAN BE CONFIGURED AS A SOFTSWITCH (SERVER), A COMPACT IP BASED SYSTEM WITH INTEGRATED MEDIA GATEWAY OR A COMBINATION OF SERVER AND MEDIA GATEWAY RACKS.

KAREL IPG is a modular and server based IP communication platform designed to meet the needs of medium and large scale organizations.

FLEXIBLE STRUCTURE
Karel IPG communication platform meets different interface requirements and integrates with pure IP infrastructures, as well as hybrid and traditional TDM networks.

HARDWARE FEATURES
Depending on the interface and capacity requirements, IPG communication platform offers different hardware options. For pure IP configurations, the system runs on industry standard servers and provides a maximum capacity of 32000 IP ports. If traditional telephony interfaces are also required, IPG500 and IPG1000 racks serve as media gateways giving a maximum of 32000 ports for TDM. Therefore, the maximum system capacity becomes 64000 ports. There is also a compact usage of IPG500 and IPG1000 racks without requiring a server. This way, a single IPG500 rack can provide 224 TDM & 500 IP ports and a 3-rack-stacked configuration of IPG1000 system can provide a maximum of 1056 TDM & 2000 IP ports.

SYSTEM FEATURES
Communication platform is an essential component of an organisation’s work processes and plays a critical role in efficiency. IPG communication platform simplifies the work processes in an organisation by integrating several services such as integrated voice response, voice mail, voice mail to email, voice logger, video/audio conferencing, presence, instant messaging, Microsoft Outlook integration and collaboration. IPG communication platform runs on SUSE Linux 12.2 operating system, which provides an open-ended architecture as well as lower processing requirements. Field tests show that even a low performance server with 1.6 GHz single-core processor and 512 MB RAM is enough to install a fully featured IPG communication platform serving to 2000 IP subscribers. Evidently, increasing the processing power increases the maximum capacity of the system.

CONVERGENCE
Developments in information technologies have already brought the concept of convergence. Today, it is not possible to think of a modern communication system independent of IT infrastructure. A telephone directory is now only a piece of data stored in organisation’s LDAP (Lightweight Directory Access Protocol) server. Likewise, authentication of a user to log into a software component through RADIUS (Remote Authentication Dial In User Service) server is also applicable for authentication of IP phones.

BACKWARD COMPATIBILITY
IPG communication platform is an ideal solution for organisations that require backward compatibility while migrating to future technologies. Compliance both with IPv4 and IPv6 is only an example.
DISTRIBUTED ARCHITECTURE
Standalone components of IPG communication platform are location independent. Server, redundant server or media gateway racks can all be distributed to different locations. In addition to typical trunking protocols such as SIP or H.323, IPG platform employs IPCC, a proprietary protocol developed by Karel, for seamless integration of servers and racks (media gateways) through an IP network. IPCC lets the distributed components of the system to work as a single communication platform. In case of a failure in communication between server and media gateways, media gateways automatically switch to self-survival mode and continue providing the same services over the internal server. This internal server is in the form of a CPU card with Qseven module and redundancy for this CPU card is also available in the system.

USER INTERFACES
All user interfaces of IPG communication platform are web based and compatible with all popular web browsers including the browsers of mobile devices such as smartphones or tablets. This gives the convenience of becoming location independent when using or managing the system remotely.

FUTURE PROOF
IPG communication platform allows growing organizations to expand their communication systems cost effectively over time.
MOBILITY
IPG Series provide a reliable and cost effective communication platform to mobile workers. Karel’s smartphone or softphone applications extend the unified communications features to smartphones, tablets or laptops through 3G or Wi-Fi networks. To keep pace with desk free people at work, IPG communication platform provides coverage through DECT base stations or Wi-Fi access points and enables a reliable cordless communication at every point.

Organisations are becoming location independent and often all workers are not in the office at the same time. Besides, some people in the office rarely need a phone. This brings the idea of saving from office resources and sharing of a telephone device. Hot desking feature of IPG communication platform lets the users share an IP phone by logging in with their own accounts. After logging in, a common IP phone becomes the personal phone of the user with his/her own extension number and customized settings. Reports of calls through these common phones will be kept as per users’ specific extension numbers. With hot desking feature, a common phone in a meeting room often used to ask for refreshments can immediately become an executive phone with extensive calling permissions and features.

USER WEB PAGE (WEB-CONSOLE)
With IPG communication platform, telephony experience of users is not limited to a telephone device. Each user of IPG communication platform has a web based interface for making calls and managing their accounts from their PCs, tablets or smartphones.

VOICE MAIL TO EMAIL
Integration of telephony with email is a favorable feature of convergence in communications. In addition to the well known voice mail feature, users of IPG communication platform can receive their voice mails as emails.

VOICE LOGGER (CALL RECORDING)
Quality assurance, performance evaluation, training or lawful interception are the common reasons of using a voice logger system. Karel IPG communication platform provides a fully integrated voice logger solution with various monitoring or storage options. In addition to local or remote storage facilities, recorded calls can be processed together with call details through WEB-CM interface or they can be automatically sent as email attachments.

CALL DETAIL RECORDING (WEB-CM)
WEB-CM software of IPG communication platform provides efficiency in storing, analysing and billing call details. It is possibleto define call tariffs on subscriber or trunk line group basis and validity of a specific tariff plan can be programmed as per various date and time parameters.

FAX SERVER
IPG communication platform supports T.38 protocol for transmission of fax messages over IP lines and employs a fax server for distribution of fax messages through email.

GSM GATEWAY & SMART CALL BACK
IPG communication platform is fully compatible with Karel GT40M GSM gateway. A common drawback of having a missed call from an organisation’s GSM gateway occurs when the called party wants to call back. As the initial call to the mobile phone has passed through the GSM gateway, called party would only see the common phone number of the SIM card installed in the GSM gateway.
Therefore, if the called party calls back the missed number, the call would be most probably answered by the operator or the auto attendant, but not by the specific person who initiated the first call. For such cases, IPG communication platform automatically diverts the call-back of missed mobile call to the initial caller.

INTEGRATION WITH OTHER SYSTEMS
It is possible to integrate IPG communication platform with various solutions through standard interfaces and protocols. Integration facilities include hotel/property management systems such as Fidelio, video conferencing, collaboration solutions, security solutions, customer relationship management solutions or call centers.

WIDEA
WIDEA is the web based management software of IPG communication platform for programming, maintenance and alarm management. Different authority levels can be assigned to different administrator accounts using WIDEA. As the software is web based, administrators have the flexibility of having remote access to the system through PC’s, tablets or smartphones.

REMOTE SOFTWARE UPDATE
All software components of IPG communication platform can be remotely loaded to the system. By just having an Ethernet access to the system, administrators can perform all the software related issues from a remote location.

AUTO CONFIGURATION
Depending on the quantity of IP phones in an organisation, reconfiguring all the IP phones one-by-one may become practically impossible. Auto configuration feature of IPG communication platform lets IP phones to be configured all together or as groups.

WEB BASED USER INTERFACES
All computer interfaces of IPG communication platform are web based. Any device with a compatible web browser can be used for accessing the system from any location.

COMPATIBILITY WITH IT ENVIRONMENT

Also, the platform is equipped with built-in Ethernet switches on CPU, media gateway and fiber optic cards. As IPG platform does not require an external Ethernet switch or fiber optic converter, related complexities of feeding or maintaining these critical components are eliminated.

ALARM AND FAILURE MANAGEMENT
IPG communication platform is equipped with an integrated alarm and failure management system. This system lets system administrators to monitor (real time), report (real time) or log the possible system faults or link/port failures. Depending on the importance of fault conditions, alarm actions may include triggering calls, SMS or email messages to predefined recipients or initiating audiovisual signals on the alarm panel. It is also possible to monitor the alarms of distributed systems on a map through the alarm interface. With four additional alarm inputs, IPG communication platform also acts as an alarm communication hub for other alarms to be triggered by other systems in the organisation such as UPS, fire alarms, burglar alarms or a like.
