"VoIP
is growing by leaps and bounds, which has increased the demands for the apps to
make IP calling possible. Using VoIP Mobile application, users can make low
cost calls from their mobiles. Apart from mobiles, calls can be made by PC
& VoIP devices."
VoIP mobile application makes calls from your
mobile phone cheaper. It enables you to call to any country you desire at the
cheapest rates. This application is currently supported on all iPhones, Android
phones BlackBerry, Windows Phones and Symbian phones. You just need to download
the free VOIP app from your APP market and register yourself with one of the
supported Voip providers. Then to make the calls you need to open the VoIP
mobile application on your mobile phone then log in with your VoIP username and
password. That’s it!
However, you might need to compromise a bit on mobility factor. Because
this application is available only within the coverage area of a single Wi-Fi
access point. But cordless protocols can offer brilliant voice support and base
station handoff, if all base stations communicate on one LAN. It generally
supports two types of communication. Cordless, DECT or PCS protocols for
short range and campus communications for broader range. All base stations in
this case are linked into the same LAN communications with the help of 3G/4G protocols.
Another kind of mobile integration uses a gateway to bridge SIP and RTP
into the mobile network's SS7 infrastructure. In this functioning,
the mobile continues to operate like a GSM or CDMA based device. The only
modification is that now it can be controlled by a SIP application server that can
afford advanced SIP-based services. With the mass deployment of
GPRS/3G/4G/Wi-Fi networks and with the introduction of cheaper data services,
calling from mobile sets using VoIP technology is getting popular.
Most of the VoIP services provided can be fully customized. It can be
branded according to the client’s requirements. They can run the dialer under
their own brand name. Consumers can easily download the dialer with full
configuration of services like switch IP, port, brand name, balance display etc.
They only need to insert PIN of their account. Nowadays, VoIP mobile applications are available on multiple platforms. These
applications can run on Symbian, iPhone, Windows Mobile 5 & 6, Blackberry
(GSM and CDMA) and Android platforms. The compatibility however might vary.
However, most of these mobile applications are compatible with Session
Initiation Protocol (SIP), Support Codecs like g729, AMR, GSM and g711 and
mostly all standard SIP soft switches.
Internet VoIP Devices let you call
other computers around the world in a similar way using a broadband connection.
Make long distance calls to landlines phones at tremendous savings. All you will
need is, either a telephone adapter connected to your home phone or landlines, a
wireless router or a network adapter card. A telephone adapter converts your standard
home landlines so that you can access other phones using the internet. It allows
you to make VoIP calls on your regular phone or landlines at cheaper and better
rates. A router allows you to network multiple computers and share broadband
internet access and other resources such as files, printers and storage. And a
network adapter allows your PC to connect to a network by cable or Wi-Fi.
It
is a VoIP device that plugs directly
into a PC using a USB port. On the other end of the device there is a telephone
cord adapter, into which you need to plug in your regular telephone. It allows
you to make calls directly through your internet and allows you to cancel the
usage of your old telephone line. For this you need to have a broadband internet
connection and your computer must be turned on while you are calling. However,
many customers complain that the voice quality decreases when they are
downloading files while making the calls. There
are cable service providers like Comcast or Verizon who offer cable VoIP
services directly. Moreover, unlike broadband VoIP devices, a cable VoIP device
promises clear call quality, even while you are downloading files. It allows
you to have faster internet speeds, cable television service and a phone, all
in one package. It is compatible to utilize a cable modem connection thus you
don’t need to compromise for a broadband connection with slower internet speed.
