Combine easy programmability with flexibility for future needs and a state-of-the-art, cloud-native platform. Learn how to switch from Asterisk to Voximplant.

Overview

Asterisk, which was founded in 1999, revolutionized telephony with its software-oriented approach to communications. Software itself has undergone several major transformations in the intervening decades. Voximplant was designed to fully leverage the distributed nature of the cloud from its inception. Needs have also changed. The early days of software telephony were largely about connecting phones. Today, developers and telephony architects are looking for a flexible platform for voice, video, messaging that can leverage the latest in AI technology. Voximplant is a modern developer platform designed for rapid cloud-based control and integration with phones, mobile apps, and web pages.

Voximplant vs. Asterisk Approach

Below are a few examples of how Voximplant compares to Asterisk in common implementation procedures.

Procedure	Voximplant	Asterisk
Setup a PSTN number to answer a call and playback a greeting	Sign-up at voximplant.com Create a new application in the GUI Use the GUI to purchase a new phone number; assign that to your application Create a new application with 5 lines of code Place a test call	Find a cloud provider & choose the appropriate server Install Asterisk Secure your firewall for Asterisk Complete basic provisioning information your info, SIP configuration, etc. Add your SIP trunk provider (assuming you have one) to the dialplan Configure your SIP trunk provider to forward calls to Asterisk Setup the Festival or Cepstral application (or other more complicated installs) Change your dialplan to play back the message Place a test call
Build an IVR based on programmable logic	Open your scenario in the VoxEngine Cloud IDE Develop your IVR Edit the code as needed anytime	Setup a development environment Find the appropriate integration library Find a cloud provider & choose the appropriate server to run your code Develop your application Deploy your application Setup the dialplan to interact with the application Coordinate updates between Asterisk and your application server
Scale to thousands of users	Nothing – scale is already included	Configure new servers Develop load balancing strategy based on your dial plan and usage Setup new Asterisk instances Duplicate and update dial plans Create a maintenance plan to keep all systems in sync

Alternatively use the SIP address provided with the Application with an existing SIP trunk provider. Then you just need to add your SIP trunk provider’s IP address to the Voximplant whitelist.
