We will try to cover all necessary details in this blog post to help you use this VoIP platform at its full capacity and not just as a SIP server. So without further holdup, let’s get started. 

1. What is a VoIP software development kit? 

A software development kit is a complete solution for developers that help them build, debug, test, and install a software solution after development. A VoIP software development kit is a comprehensive set of tools, frameworks, compilers, debuggers, and other essential components required by VoIP developers to build a comprehensive VoIP application. 

Depending on the VoIP platform or technology, the VoIP solution development kit can give different tools and frameworks along with a compiler and debugger.

2. What is OpenSIPs? 

OpenSIPs is an acronym of Open Session Initiation Protocol Server. It is also referred to as an open source SIP proxy program. Originally, it was used by OpenSIPs solution development companies as a SIP proxy server. It retransmits the SIP requests received at this server after evaluating and classifying them to the specified destination. It can also transmit requests to more than one destination, all in one go or one by one. 

It is also used as a proxy server, load balancer, router, switch, gateway, application server, and registrar server. However, it is not yet explored as a comprehensive software development kit by VoIP development companies. But, it is a complete software development kit that can be used to build cutting edge applications to empower VoIP businesses. 

In the following pointers, we will explore a technical guide to use it as a software development kit and build an app with OpenSIPs customization. 

3. What are the steps for OpenSIPs installation? 

Steps For OpenSIPs Installation

To use this platform, the first step will be installation of this platform. This technical installation guide can be used to install it on Ubuntu for any purpose. It can be installed for standalone or embedded configurations. 

Whether you want to use it as a load balancer or as a software development kit, you need to install it first. 

  • Download the latest version of OpenSIPs. You can find it here on the official website of OpenSIPs, here. 
  • Run this code: tar xzf open siips-1.5-1.tar.gz. This will help you extract the downloaded software. 
  • Run this code: cd open siips-1.5-1. Once your software is extracted, running this code will change the directory. 
  • Run this code: sudo. /install 

This will take some time and install OpenSIPs to use for any purpose you would like to achieve with this software. 

4. What are the available SIP configuration options for OpenSIPs? 

There are multiple options available for SIP configurations with an OpenSIPs server. Following are some of the popular and useful options that can be set from different locations and in some cases, multiple times. Following are the available options: 

  • Choose the interface type: TCP or UDP 
  • Interface IP address configuration

5. How to create users for voicemail? 

Once installation and configuration steps are completed, the OpenSIPs development company or OpenSIPs developer can configure different VoIP applications and services. Voicemail is one of the most widely used applications, so we can help you build it with the OpenSIPs development kit. 

You can create users and groups for voicemail with OpenSIPs using a GUI based app. To create users, follow the below mentioned steps: 

  • Browse to the user management tab 
  • Click on the “Add User” option 
  • Add the required information 

These steps will create a user in the SipXecs user account. 

6. How to use the PSTN gateway in OpenSIPs? 

You can configure the PSTN gateway in OpenSIPs by configuring SS7 routing. This routing bridges the VoIP network and PSTN and provides a routing facility. This is necessary to use the voicemail feature if you want to take advantage of PSTN or VoIP calls. 

7. How to configure SS7 routing? 

It is very easy to set up SS7 routing for PSTN to VoIP routing. Here are the steps to follow: 

  • Configure your gateway. You will need to use your credentials for this configuration in OpenSIPs. 
  • Provide the gateway as an outbound proxy server to configure the SIP trunk. You need to have the required SIP trunk and configure its details in this step. 
  • This step will require you to set up a VoIP trunk as an outbound proxy server. It is possible by configuring the gateway. This needs to be done with bidirectional configurations to enable two-way communication for the voicemail feature. 

Once you complete the configurations as mentioned in the above mentioned steps, you have configured and developed a voicemail app that can be used in your OpenSIPs solutions. You have developed the voicemail feature. It is as simple as you find it, but yes, you need to know how to make the right configurations.
