Asterisk®* is a free and open-source framework for building custom communications systems. While being free sounds ideal, Asterisk® is not a ready-made system and requires specialized knowledge to set up. Support and training is often very costly. What’s more, Asterisk®-based systems such as Digium®*, FreePBX®* and Switchvox®* require you to buy a large number of expansion modules. The Linux edition of 3CX includes all the functionality of Asterisk®-based systems but without the management and deployment headaches. Everything is bundled in the price, making 3CX the ideal Asterisk® alternative!
