We needed to connect our in-house RTC technology to the FreeSwitch servers. In order to complete this integration with the payment system, engineers from Mongolia, China and India talked online and completed it quickly and efficiently. We started working together because the iNextrix staff was very skilled and connected during integration and installation phase. We are glad to meet and cooperate with iNextrix team with high knowledge of VoIP technology and billing.

We were lucky to find iNextrix.   We began using their enterprise billing system.  It help us invoice customers accurately and on time.  It gave us the ability to track sales and carrier usage. When customers needed softphones for their call centers INextrix prepared their white label softphone and skinned it for use by our customers.  They are an integral part of our VOIP services.

ASTPP has been our switch of choice for wholesale voice termination since 2013 – a lifetime in this industry!
Over the years we have seen customers and suppliers change their switch chasing features, however, the open-source model for ASTPP allowed direct code changes to add features straight into the switch.
iNextrix/ASTPP team have built a truly open system and combined with their commercial support packages we have leapfrogged wholesale voice competitors with features not available on other switches.
I can whole heartedly recommend ASTPP for commercial wholesale voip.”

After some months of searching for a complete VOIP platform, ASTPP was the winner and we have never looked back.
We also recommend the training that is a great shortcut to be up and running in no time.

I’ve been a customer of ASTPP for over a year now and like most of you reading this was looking for a cost effective high quality call billing platform. I took the plunge and was really impressed with how clean the solution is and how proactive the ASTPP support team are. What really impressed me though is their willingness to adapt the solution or even build out brand new bespoke products including real time speech to text engines. They are now my go to company when I want an inhouse products developed. Give them a try – their product stands up to international resilient call routing quality expectations and their service and support simply cannot be matched. I’m a very happy customer.

The earlier switch we were using was expensive, yet it failed multiple times in safeguarding us from hack attacks. It was a major concern for us along with other issues we were facing because of it. We are glad we get in touch with ASTPP team. They provided us the solution we were looking for. We are still using their support services and I recommend their professional service.

Astpp is a good product (definitely the best i tested so far)… The technical support team (Devang and Akash) or Amit from the sale team have been very good as well. They are promt and professional and i would strongly recommend contacting them for your astpp requirements or VoIP support.

After years of struggling with Freepbx Billing solution that didn’t quite live up to our needs integrating ASTPP into our platform has proven to be well worth the time. With small customizations here and there ASTPP has helped us build a platform we can rely on.

Having used other opensource billing solution, I finally tried ASTPP and after few tweaking and I was up and ready to scale up my business within one year. At the moment, ASTPP is the only true opensource billing solution made for commercial scale traffic on planet Earth. That is true that I had to left proprietary commercial scale billing solution as ASTPP gives me much more benefits and control. Hats off to the ASTPP team for the outstanding product.

We have been using ASTPP for years and have never looked back. It’s a reliable platform and is cost effective.
Freeswitch works well across all hardware products we’ve had to work with. The support crew is fantastic and have never failed to help, even going beyond the call of duty at times. We had some customization done on our server and our ROI has always been quick. It’s a simple UI so even my admin staff could learn to use it in no time at all. Well done ASTPP.

We use ASTPP billing system about 2 years for internal proposes even from 1.7.3 version without any any problem. ASTPP is working absolutely fine with FreeSwitch really fast and do that it says. The most important is that when we need help of something or we need any customization we are able to get it from ASTPP support team and specially from Mr Samir. Personally I suggested ASTPP Billing system.

It was great experience by working with ASTPP team and for-sure in future too. They are very much pre-advance who believe to focus on client productivity very closely to make sure follow consistency. ASTPP Team approached me to upgrade by outdated version into latest version and gifted me high ROI. ASTPP is best softswitch I have ever came across because of it’s great UI, Smooth Billing Process and long reliability.

Thank you for a great solution and your opensource initiative. I am new to ASTPP and I am trying out, so far, I feel that ASTPP may meet my needs after some tests. I bought this FreeSwitch Monitoring package addon to show my support to your team’s hard work and also see it to be a really useful addon. I will also order support package later when I am more familiar with ASTPP.
