Basics Of IP Telephony
Telephone systems of today still do what they’ve always done, which is answering, dialing, holding and transferring calls, which are very fundamental features that one can’t live without. On the other hand, the way phone systems of today are interconnected to other systems as well as technologies is what really interesting. Most of the day to day tasks are now automated and the telephone systems made valuable contributions to increase productivity of staffs while being able to lower operational costs.
The voice traffic has took a big turn when it comes to transmission method in and around the year 2000. What was known before as circuit switching where callers used point to point path to make a voice call, something called VOIP or Voice Over Internet Protocol has become a reality and the packet switching is now a new standard to follow. The developments in data networking, internet quality and wide area networking has allowed calls be sent across the web all over the world at a pace that issues in quality are diminished.
Most of the phone system suppliers offer IP enabled or Pure IP solutions. The IP enabled telephones mean that the conventional digital phone systems are adapted to support the VOIP technology. In most instances, Pure IP telephone system is based on pure IP switching methods and is capable of providing more integration and better scalability with 3rd party systems as well as software. In basic form, the VOIP allows the broadband users to make a call across the web without being charged. On the other hand, if you have used Skype or other video messaging app, you probably know that the other person has to use the same app or software first and subscribe to the same service in order for this to work.
Incredible Lessons I’ve Learned About Options
As for these so-called free services, what seems to be the downfall that many people find is, users should be online and logged in to their account in the same platform. To be able to make normal calls to someone on a mobile or landline, you should break out from VOIP network and this is where the call is charged.
A Quick Rundown of Systems
By allowing every office location with VOIP based telephone system, you can link each location together with the internet. And by the time it is successfully linked together, then it’ll make internal dialing across the location to be free and seamless. Aside from that, this also provides many benefits similar to saving costs of using a BT to make inter-branch call, centralized management as well as application sharing, overflow/transfer calls from one site to the other and unified extension numbering plan.
