Fasten your seat belt and gear up for a mind-blowing jolt to the world of VoIP. Let the music begin, we are going to explore Kamailio, WebRTC and FreeSWITCH in deep. Oh, I like to view them as the active pair (well, actually, the big triumvirate) of your communication kingdom. Now let me explain how these industry giants can enable you to deliver mind-blowingly amazing VoIP experiences.
Kamailio: The Traffic Cop
It is rather easy to imagine Kamailio as the ultra intelligent traffic police controlling the calls. It is the mastermind for the overall system facilitating call routing, user registration and overseeing the overall procedures. This is such a relief for any person knowing that they have a call manager that is as efficient as a ninja, all days of the week.
WebRTC: The People's Champ
WebRTC is real-time communications’ people’s hero. I can only wonder how people were able to collaborate on a project, share a screen, and similar without this good-old technology. A social fabric in other words can be regarded as the common revelry of the people, where everyone is drawn.
FreeSWITCH: The Versatile Performer
FreeSWITCH can be categorised as the most ‘’jack of all trades’’ type software out of those presented in the list above. This is versatile for voice, video, messaging and many others. In other words, it is versatile in communication as would be averred by tool’s usability where people considered as clients are concerned.
How Do They Cooperate?
Kamailio is the brain, controlling calls, and users while OpenSIPS is at the executive level.
As for the real-time media, this is WebRTC’s responsibility; it deals with the audio and video.
FreeSWITCH is an application with productivity features and acts as a mediator while handling media and/or several protocols.
Combined, they produce a synergistic effect that can yield splendid, noise-free VoIP communication.
Hacks for Crystal-Clear VoIP
Optimize Network Performance: See to it that your network has ‘speed’ written all over it. One may also compare a slow connection to a situation when people attempt to speak to each other in water.
Leverage Codecs Wisely: The choice of codecs for your audio and video should also follow proper codec selection. It is as if choosing the appropriate Wear for the Event being held.
Implement Echo Cancellation: It is not fun answering a question and hearing the sound of our own voice that reverberates within the room. Output echoing is your ace card against this nuisance.
Error Correction: It is for this reason that even the best laid out networks fail due to some occurrences in people’s lives. It is used as a desperation technique to ensure you do not derail your calls.
Jitter Buffering: Remove those glitches in the audio stream with jitter buffering. It is like adding a protective barrier or intermediacy to what you are saying.
Experiment and Fine-Tune: This means that you should not be afraid to try out the various options provided by the particular software. So of course every situation is different and your best bet would be to decide on what best suits you.
