VoIP also called as Voice over Internet Protocol, Voice over Broadband, Internet Telephony, IP Telephony, Broadband Phone, and Broadband Telephony refers to the voice routing conversations via Internet or any other network that are IP-based.

Below are the features of many VOIP providers offer for telemarketing campaigns used by outsourcing company businesses or what they called their virtual assistant.

UNLIMITED CALLING

Almost all VOIP providers have been offering total calling. Unlimited does not clearly mean "unlimited". Almost all VOIP providers SAY unlimited, though for home VOIP use, what they clearly MEAN is "rationally unlimited". If we begin regulating some-more than about 3000 to 4000 minutes per month of call time, you might get a notice about it, or they might even close you off. Commonly, especially during commercial operation company’s telemarketing campaign uses VOIP phone, a programmed auto-dialer do calls.

CALLER ID

Caller ID is for inbound calls but VOIP providers requires an "extra charge" because packages like outbound and inbound calls are separately served.

CALL BLOCKING

With this feature, we can hold back certain calls from entering. Again, this can be customized in addition from your phone for your unchanging phone lines, however additional charges may require.

CALL WAITING

Obviously this is for incoming or inbound calls; listen to a tone which alerts you about an additional incoming call. You can press "flash" in between the calls.

Aside from its features there are different VoIP services commonly used today, here are some examples:

1. ATA is the most common and simplest way of service using the Analog Telephone Adaptor device which converts analog signals to digital signals. It allows standard phone connection to your computer or internet connection for VoIP use. The converted analog signals are transmitted on the internet.

2. IP phones are specialized phones resembling normal phones with cradle, buttons, and handset. The only difference is that a phone connector (RJ-11) is used by standard phones while an Ethernet connector (RJ-45) is used by IP phones. IP phones are directly connected to the router with all the necessary software and hardware in handling IP calls. IP phones that are Wi-Fi will also soon be available. VoIP calls can be done at all Wi-Fi hotspot.

3. Computer-to-computer is the easiest method of using VoIP. Calling long distance is free. There are a few companies which offer free or very cheap software to make use of this method. The user only needs a microphone, sound card, speakers, Internet connection (via DSL modem or cable) and the software. However, the users need to pay the ISP monthly fee.

The advantages of VoIP service include drastic reductions in costs for international calls, and the elimination for the need for workers to be tied to one location. Employees can be moved from one office to another and retain their personal phone extension. Telecommuting becomes easier and costs continue to drop for communications and data networks.

As VoIP continues to mature, more sophisticated applications and features are being added. VoIP calls can now be made to cell phones and traditional landlines, increasing compatibility and ease of use. Regular telephones and handsets are now capable of supporting VoIP routed calls, and modems have been developed that can plug into a wall jack and take over an entire business office or house’s phone wiring.

Be it in office or at home, telephone is one of the fastest and reliable means of communication. If you are looking for an economical and effective means of communication for international calls, then VoIP is the ideal choice.
