Asterisk Vs FreeSWITCH

asterisk vs freeswitch

 

After the clarification of this two communication platform, we move further to discuss differences between FreeSWITCH and Asterisk.

 

Scalability

 

Asterisk is not the good platform for the higher volume of calls. Becuase it used shared resources therefore in the case of provisioning calls it is not a sutiable platform. In a case of high call volume, you can encounter occasional deadlocking, race conditions, and potential data corruption. While on the other hand FreeSWITCH is scalable communication platform. It can easily handle high capacity volumes of call. In scalability case, FreeSWITCH is the better choice for those who want to utilize high volumes of calls.

 

Configuration

 

Asterisk use a simple file for dial plan and configuration. Therefore, we can say that configuration of the asterisk is simple. While FreeSWITCH uses XML file for configuration and dial plan. It consists of manual configuration and maintenance. XML has its own method of writing the file. It is little difficult. So we can say that Asterisk is more easy to use as compare to FreeSWITCH.

 

PBX And Softswitch

 

The biggest difference between two communication platform is, Asterisk is PBX(private branch exchange)solution and framework for developing communication applications. While FreeSWITCH is just a Softswitch.

 

Flexibility

 

Both applications are flexible in use. They provide the features of expandability. We can say that FreeSWITCH is more flexible as compared to Asterisk. Because FreeSWITCH supported multiple languages such as .NET, JavaScript, Perl, C++, Python, and FreeSWITCH library easily embed with other applications.

 

Licensing

 

Asterisk comes with dual licensing. One license of Asterisk is free and other is proprietary. The free license comes under the general public license. While FreeSWITCH is completely free communication software solution. It is released under the Mozilla Public License.

 

Asterisk Vs FreeSWITCH battel – Which one is better

 

After analyzing these two applications we can say that both applications have some advantages and some disadvantages. Its totally depends on the user which features its needed for the deployment of a communication system. If its target to utilize the huge volume of calls than FreeSWITCH is the best choice. But if a user needs easy configurable and low volume of call than Asterisk is better solution etc.
