Asterisk

Commentaires: We use this everyday for our phones. We test a variety of platforms on a regular basis, but we have always stuck with Asterisk because it does everything we need.

Avantages: Asterisk has nearly everything you would need in a phone system for a small business. With some technical knowledge you can get the free version of this and do everything yourself with very minor costs to your bottom line.

Inconvénients: The learning curve on Asterisk systems is steep. If you want to do anything custom, you will pretty much have to hire someone to do it for you unless you have a lot of experience and technical knowledge. Much of this can be overcome by using a GUI such as FreePBX.

Commentaires: This software allows to solve or implement any solution for the telephony industry.

Avantages: Asterisk more than a software, it is a framework. As a framewaork, it is like a Swiss army knife that allows you to implement or solve any special requirement in telephony, call center, messaging services, etc. Asterisk is the base of a number of solutions for telephone centrakes. It is also easy to get in the market all the necessary hardware to connect with the PSTN switched network.

Inconvénients: I am a fan of Asterisk. However I am surprised that to date, we are going through version 15, and the last textbook was printed in 2013, on version 11.

Avantages: This is the BEST VOIP software you can use. First of all its a free base. It has so many features that are amazing for small and large business setups. You can buy really cheap analog lines and hook up to this system. And just use your own phones. It saves 1000's of dollars each year from competitive voip systems.

Inconvénients: The software can be buggy when first setting up and interfacing cards. It works great but if you are not familiar with command promp you will not be fully able to set it up.

Commentaires: It works for what we do.

Avantages: The amount of features that you can get with this software is astounding.
If you have the time and the know how you can make this software do it.
We use it every day. We have about 35 techs answering calls
It will run on just about any computer that you have.

Inconvénients: It is very complex.
Like all things in the Linux world it is difficult to setup the first time you use it.
It is very difficult when you want to change hardware or make system level changes.

Avantages: Easy and cheapest way to setup a VoIP system. Used this product for more than 12 years. There was number of versions during this time. Very reliable and the system can even work as a Windows VM. Since the UI is user friendly and heavily customizable, this is a very good product for small/medium size business.

Inconvénients: I would like to see an option for the end user to select what they need while installing the distro instead of ISO installing everything.
