VoIP is simply the transmission of voice traffic over IP-based networks like the internet. IN a nutshell, internet is designed for data traffic only but the success of IP (internet protocol) in becoming a world standard for data networking has led to voice networking. It has become popular largely because of the the enormous monetary savings it gives to the consumer. Switching to VoIP technology have more advantages over traditional telephone networks especially for international calling. How much does a single 15 min. long-distance call costs? A lot. If you use Skype, it’s free.
Do you know that call centers here in the Philippines use VoIP technology? Imagine if they’re using PSTN or the traditional telephone networks, catering to at least 1000 calls a day, I ‘m sure wont be able to survive with the per-minute long distance charge.
My current job deals with networking and it covers a wide range of topic including VoIP. I only know a little about this technology. I still have a lot to learn. I’m currently enrolled in a Cisco training course to become a CCNA, hopefully. Yes, it’s nosebleeding yet I find it really fulfilling, career-wise.
