Telephones & VoIP
Telephones ruled the communication field for a long time and they will continue to do so. PSTN or IP PBX, phones are required.
When Voice over Internet was designed, probably, they may not have envisaged that phones can be used to leverage the same so quickly. VoIP was designed to communicate through internet using Microphone and head phones.
Then Skype entered the field and innovative manufacturers brought out a phone that can be connected to internet and make calls as if you are using a regular telephone line. The difference is that, it is connected to your internet.
New Adapters are introduced that can be plugged into the Internet one side and the regular phones are plugged into the other side. Using this adapter, ordinary telephone can work on VoIP.
New developments in future will see dual-mode IP phone that works as WiFi phone inside the building/campus and as cellular phone outside the network.
We are likely to see cellular phones in future with software that can identify the location of the target and routes the call to the user by identifying the best available connection. If a user receives a call at the workplace IP PBX number, the PBX checks if the person is available at the regular telephone extension. If the person is not reachable, it looks for the person’s cell phone and routes the call to the cell phone. Here, the difference in rates of call will be an issue. Who pays for this? Enterprise is expected to pick up the bill as people and communication are important to any business.
Cell phones are likely to become intelligent. The equipment installed in shopping malls, will know where you are at a particular time. They follow you where you go and when are next to apparel store, a message will prompt you to enter into that store to avail discounts. And this discount may be just for 5 minutes, to tempt the buyers.
Similarly, when you are in a conference, you may set the parameters you are interested in as well as define your preferences. The system searches for similar profile and establishes a contact. These can be made possible using VoIP.
A typical VoIP USB Phone may be supplied with an LCD screen to show call information, call time, time and identify which of your contacts are online and available. The main features include controls for your voice, ring and key tone volume. To make it fun to use, many ring tones will be made available. One can make and/or receive phone calls even if the monitor is turned off. Echo cancellation and noise reduction are taken care of.
The audio is independent from the computer and you can listen to music or play a game while making a call.
Other typical features are PC-to-PC and PC-to-phone operation, compliance with USB1.1 specification and compliance with H.323, MGCP, SIP protocol.
These neither need a sound card nor the external power supply. Handles Full duplex communication.
When it comes to software, they generally support Windows 2000/XP/Me/98 in OS and come with VoIP Software compatible with MSN, NetMeeting, Yahoo Messenger, Skype etc.
Generally these products require an existing internet connection for operation. The keypad can only be used with VoIP telephony programs, which may require subscription and/or additional cost.
Main advantage in future will be your ability to carry your wireless VoIP phone anywhere you want and enjoy the same number. Imagine a phone in future , your wireless VoIP phone tracking the nearest Internet service provider, login into the network and you are ready to talk!!
