    Kamailio SIP Server is very well suited if you want to secure your main servers; it can perfectly act as a proxy server and a gateway to your main server. It also does load balancing and call transfers easily based on the configurations done.

    Telonium enables us to keep your voice systems automated, allowing us to receive all incoming calls and route them to the appropriate person in your office. We are notified whenever a voicemail message is left on your desk. You can play the voicemail without dialing if you receive an e-mail notification.We can customize our phone system from anywhere. There is no need to schedule a technician to visit your site and make adjustments because all phones are delivered ready to connect. We can use this program to prevent unsolicited telemarketers and phone calls from reaching our phones. It is the ideal solution for a better and safer phone service, with a high percentage of filtered calls in our favor. Telonium makes it as simple as possible for us to launch or relocate your service. When our customers and prospects call you, we only need to provide a few pieces of information, and Telonium will handle the rest. When you need to make changes to your system, all it takes is a phone call or a visit to a customer web portal to make immediate changes.However a high-speed Internet connection is required at the location where the phone will be used.

    • The control panel function is very good because we can see the progress and work of the agents, individually and also as a group with the different work teams.
    • We have found the call scripts very useful, especially with new agents who still don't know very well how to conduct the conversation with customers.
    • I think the omnichannel support is great because all the communication channels are in the same program, which makes our work easier.

    As Kamailio SIP Server is an open source, the major impact is on cost; it's free to use compared to any other Softswitch or server in the market. You can also customize it to your need and use the features that you need, which is one of the major plus points for the Kamailio SIP Server. And one server is enough to handle thousands of calls simultaneously.

    • We can see how our agents and customer service staff have become more focused on their tasks and have been more effective and successful in resolving customer requests. The system is quite easy to install and use, so we didn't have any inconvenience, so without a doubt, our profit margin increased.
