IP Telephony PBX PBA Doha Qatar empowers businesses with a much broader range of functionality and capabilities to make their business much more efficient in a modern working landscape. Below are just a small selection of the numerous advantageous features of an IP phone system (IP PBX).
HD voice: Essentially ëHigh Definitioní voice means users can leverage a more seamless, clearer quality of sound that wipes out background noise.
One number: Investing in IP technology allows users to have one single phone number to call from different handsets.
Least call routing: Least call routing (LCR) allows you to economise by letting the system automatically establish the best way to route your calls. This ensures that the pre-set, lowest cost option will be selected as the routing path for each external call.
Call handoff: Call handoff is a feature that means users can switch from one device to another seamlessly and without audible disruption. For example, users coming to the end of their day can switch from a desktop (softphone) to their mobile device to continue their call as they shut down.
Fixed-mobile convergence: For many roles such as sales and client servicing or support, businesses need an ëalways oní model for these profiles. Fixed Mobile Convergence means that a mobile phone can act as another hub with all the functionality of the phone system including call transfer and conference features etc.

What is the difference between Internet Telephony and Voice over IP?
Internet Telephony and Voice over IP (VoIP) are often used synonymously, but in reality, VoIP is a subset of Internet Telephony that refers to voice traffic only. While Internet Telephony is a general term for the IP packet-switching technology used by Internet phone systems to exchange any type of information, Voice over IP is the specific method for carrying voice calls over an IP network. Internet Telephony includes VoIP capability as well as a host of other features and functionality. For example, with Internet Telephony from NFON, it is possible to integrate Unified Communications (UC) and fax solutions over XCAPI.
How does an Internet Phone System Work?
In order to use an Internet phone system, it is necessary to have a VoIP solution such as the NFON Cloud Telephone System.
As you speak through a microphone (laptop, mobile or headset) your voice – the audio signal – is digitised. This data is split into packets and given individual labels.
Your call is made up of different packets of data. Each packet of data travels over the Internet to the recipient. When the data arrives at the end destination it is put back into the correct order. The data is then converted into audio and the recipient hears what you said.
Interestingly, the data packets donít necessarily arrive in the order they were sent: they can overtake each other en route. When then arrive they are reassembled in the correct order and your message can be heard by the recipient.
