So what does 'free' really mean when we're talking about a VOIP service?

Many Video Management Software (VMS) providers offer free versions, either open source, for a limited number of cameras, or for a limited amount of time. Minimal Changes in 2021 The free VMS market has shown minimal changes over 3-4 years, with limited adoption of free open source offerings. Enjoy a free softphone, video chat, video conference calls, auto attendants, voicemail-to-email, call management, queue reporting, and so much more. And with the free OnSIP app, available on Android, iOS, Mac, and Windows, you can use your mobile phone or computer to make HD voice and video calls, view coworker presence, dial contacts with a click, and manage your voicemails.

Does it mean free phone calls from your PC to another PC, from your PC to phone, or from one phone to another?

VOIP providers also toss around the word 'free' when it comes to what's included their subscriber plans. For example, Vonage UK offers its customers 'free' calls to the US anytime...In this case, free just means the cost of the call is include in your monthly rate (which is still very reasonable).

However, for the purposes of this article, free VOIP refers to the free VOIP software offered by companies like Skype that allows you to make free PC-to-PC, PC-to-phone, or phone-to-phone calls.

Is there a hitch? Sometimes, and really not so much a big deal. For example, in return for allowing you to make free phone calls, the VOIP service provider may ask you to view advertisements or to log on to a website and provide personal details.

There are three types of VOIP services:

Free PC-to-PC VOIP Services

To make free PC to PC VOIP phone calls you need two computers with Internet connections, a sound card, microphone and speakers or headphones. You don’t need any special service, though you will have to install the free VOIP software on both the PCs. A few of the companies offering this type of free download are: Skype, Gizmo Project, Free World Dialup, BuddyTalk, and now Google Talk and Yahoo! Messenger with Voice.

You will not be able to make a call if both the computers are not running, or are not loaded with the right software. This limits the utility of this service but it is still a good option because many service providers have stopped offering free PC to phone services.

Free PC-to-Phone VOIP Services

To make free calls from a PC to phone, you need a computer with a sound card, a microphone and speakers or headphones.

The voice quality is quite good, though it does not match a conventional phone. A poor Internet connection can cause a drop in the sound quality and an increase in the lag. Bugs in the software can also create problems. It helps if you download the latest operating system and update your browser. Most of the service providers in this category have gone out of business and some have begun charging for their services.

At the time of writing, one company offering free computer-to-phone calls is Voipbuster.com. You have to download their VOIP software which you use to make calls from your computer. Calls to other Voipbuster customers are free, as well as calls to landline phones in the following free destinations: Australia, Austria, Belgium, Cyprus, Denmark, Finland, France, Greece, Hong Kong, Iceland, Ireland, Luxembourg, Monaco, Netherlands, New Zealand, Norway, Portugal, Spain, Taiwan.

Free Phone to Phone VOIP Services

This service allows you to make free calls from one phone to another. In return you may have to visit websites, view advertisements or subscribe to partner services.

Unfortunately, this type of free service may have already gone the way of the dinosaur. At the time of writing, companies such as extremevoice.com and speak4free.com are no longer offering this service.

A freeware utility to spoof MAC address instantly

Version 6.0.7

Windows 10/8.1/8/7/Vista/XP/Server 2012 R2/Server 2012/Server 2008 R2/Server 2008/Server 2003/Server 2000

Technitium MAC Address Changer allows you to change (spoof) Media Access Control (MAC) Address of your Network Interface Card (NIC) instantly. It has a very simple user interface and provides ample information regarding each NIC in the machine. Every NIC has a MAC address hard coded in its circuit by the manufacturer. This hard coded MAC address is used by windows drivers to access Ethernet Network (LAN). This tool can set a new MAC address to your NIC, bypassing the original hard coded MAC address. Technitium MAC Address Changer is a must tool in every security professionals tool box.

Softphone App For Mac

Features

• Works on Windows 10, 8 & 7 for both 32-bit and 64-bit.
• Enhanced network configuration presets with IPv6 support allow you to quickly switch between network configurations.
• Allows complete configuration of any network adapter.
• Command line options with entire software functionality available. You can select a preset from specified preset file to apply directly.
• Update network card vendors list feature allows you to download latest vendor data (OUI) from IEEE.org.

How Does It Work?

This software just writes a value into the windows registry. When the Network Adapter Device is enabled, windows searches for the registry value 'NetworkAddress' in the key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E972-E325-11CE-BFC1- 08002bE10318}[ID of NIC e.g. 0001]. If a value is present, windows will use it as MAC address, if not, windows will use the hard coded manufacturer provided MAC address. Some Network Adapter drivers have this facility built-in. It can be found in the Advance settings tab in the Network Adapter's Device properties in Windows Device Manager.

How To Change MAC Address

1. Starting MAC address changer will list all available network adapters.
2. Select the adapter you want to change the MAC address. You will get the details of your selection below.
3. In the Information tab, find the Change MAC Address frame. Enter new MAC address in the field and click Change Now! button. You may even click Random MAC Address button to fill up a randomly selected MAC address from the vendor list available.
4. To restore the original MAC address of the network adapter, select the adapter, click Restore Original button in the Change MAC Address frame.

NOTE: This tool cannot change MAC address of Microsoft Network Bridge. Network Bridge will automatically use the original MAC address of the first NIC added into bridge with the first octet of MAC address set to 0x02.
