IP Audio Conference System


 

Uses

Basic uses of the IP audio conference system

The PJP-50R offers audio conferencing using IP communication functions.

The PJP-50R audio conference system features Yamaha technology and is designed with IP communication functions that make remote conferencing easy on both listeners and talkers.

This configuration requires an established network that responds to a ping and has open 5060 (UDP) ports for SIP and 57000 to 57010 (UDP) ports for RTP/RTCP.

Ideal for communication between locations

The PJP-50R is IP audio conference system with built-in IP communication functions. You can immediately set up an in-house conference with multipoint connections using an existing corporate LAN, with no call/communication charges. This system is ideal for communication between offices/facilities within the company.

Making and receiving IP audio conference calls

Calling and receiving on this system requires no complicated settings. For example, to call Bangalore from Tokyo, simply enter the Bangalore office's IP address (in the example above, 192.168.30.173) and press the Call button. The party on the other end (Bangalore) presses the Receive button and the call begins.

Connection with up to eight locations

The PJP-50R supports audio conferences connecting up to eight locations (up to four mesh and eight cascade connections) without an MCU (multipoint connection unit).

Key benefits of the IP audio conference system

Easy to connect

image

An audio conference between remote locations can be started immediately by connecting to an existing corporate LAN and allocating an IP address to Yamaha's IP audio conference system (PJP-50R). No complicated configuration or settings required. Simply by entering the IP address of the party you wish to reach — just like a telephone call — you can immediately experience high-fidelity audio conferencing with ease .

 

High fidelity

Transmissions by the 7 kHz-bandwidth IP audio conference systems cover almost all frequencies of the human voice (when using G.711 extended code), or approximately two times that of analog phone lines (3.4 kHz). The high fidelity is therefore not only "easy on the talkers" and "easy on the listeners," but also creates incredibly realistic conversations in which speakers are easily identified simply by the sound of their voices.

Multipoint connection

The PJP-50R supports audio conferences connecting up to eight locations (up to four mesh and eight cascade connections) without an MCU (multipoint connection unit).

Location independent

The adaptive echo canceller on Yamaha's conference systems "studies" the operating environment and automatically adjusts the echo-filter factor accordingly. And since it performs well in many different acoustic conditions, you can easily hold conferences in whatever space is available. Video conferencing systems tend to require a designated room and complicated setup. But with their integrated microphone speakers, the PJP-50R is portable and easy to set up anytime, anywhere there is a LAN.

Toll free, and no charges for multipoint connections

When you use the PJP-50R with your existing corporate LAN, calls are free of charge. And because multipoint connections are basic functions, there are no multipoint connection service fees. Also, if you set the PJP-50R for always on IP communication between locations, you can create a "speak-answer anytime" environment at low operating cost.

 

Specialized uses for the IP audio conference system

Combining with a Web conference system

When you combine the PJP-50R with a Web conference system, you can hold a high fidelity audio conference while sharing materials with remote locations. By keeping the PJP-50R's audio calls separate from the Web conference session, the audio remains stable and unaffected by the Web conference network or PC. Also, since the audio is maintained even if PC troubles or other factors cause problems on the Web conference line, the conference can continue even if video is lost.

How Web Conferencing Works

Combining with a network white board

By connecting the PJP-50R to a network white board—in which any notes written on the white board at one location are visible on the white boards at remote locations—parties can convey meaning in even richer detail.

Combining with a LAN compatible projector

If the PJP is connected to a LAN compatible projector in which a PC screen can be projected simultaneously on multiple projectors, you can easily give presentations in remote locations. By adding the PJP-50R, you can take full advantage of the projector's LAN functionality.

Combining with a network camera

As with video conferencing, you can achieve two-way exchanges of images and audio. It is also possible to give instructions, for example, while viewing images from remote locations.

Equipping a remote office with an always on IP connection

When you use the PJP-50R with your existing corporate LAN, calls are free of charge. You can easily set up a remote office by opening an always on IP connection on the PJP-50R between locations. For example, with an always on connection between offices in Silicon Valley and Seattle, you could speak to your distant colleagues at any time and expect to hear an immediate answer. Or, imagine programmers in remote development labs talking with one another about joint development projects as if in the same room, having their hands free to type code.

 

How IP an audio conference system help business

Improves business productivity

The volume of corporate communications is rising dramatically.

By introducing an IP audio conference system into your workplace, you can easily hold conferences with remote locations anytime, anywhere. Moreover, it allows you have group meetings with multiple participants across multiple locations, and instantly eliminates the inconvenience of fixed video conference rooms that require reservations and scheduling. Given the increased importance of work coordination when team members are spread across multiple locations, business productivity can be dramatically increased through information sharing and real-time communication.

Increase effective working hours

Reduces business travel time, increasing the ratio of time spent on primary duties

Installing an IP audio system is a sure way to shrink the time spent on business travel and moving between facilities, while offering the same rich communication that was once only possible in face-to-face meetings. Since the person in charge need only attend the conference remotely during key discussions, a business trip that once would have included multiple persons can now be handled by just one representative. Also, you can raise the efficiency of meetings on business trips by holding pre- and post- meetings before and after the business trip via the IP audio conference system.

Cuts costs

Reduces travel expenses, phone charges, and other incidental expenses.

Using an IP audio conference system can reliably reduce business travel and other incidental expenses. Furthermore, the IP connection means no phone charges when you use your existing LAN lines. Unlike with video conference systems, there are no usage charges for dedicated lines or multipoint connection services, nor any need for expensive equipment.

Reduces business trip CO2 emissions

Environmentally responsible companies are placing priority on reducing CO2 emissions.

When business trip frequency is lowered through IP audio conferencing, the amount of CO2 emitted from transportation is also greatly reduced. Thus, the PJP not only increases business efficiency and cuts travel costs, it also makes a significant contribution to reducing CO2 emissions.

Effective for contingency planning and risk management

Utilize the PJP as an effective backup tool for your phone line, and for remote conferencing when trouble occurs.

IP audio conference systems are even useful during accidents and disasters, supporting multilocation remote conferences as a backup system when phone lines go down, or when holding emergency meetings with remote locations during a crisis. They are also very useful tools from the point of view of risk management, because they facilitate coordination with remote locations when employees are injured or sick and have difficulties moving between sites.
