“A rollercoaster journey that came good!”

Overall rating5.0
Ease of use5.0
Features & functionality5.0
Customer support5.0
We had been using an existing solution for 15 years and whilst it was still working well it was end of life and no updates were possible. Due to the size of the project involved we kept pushing it to lower priority, something always became more important!

I began researching and found ASTPP would manage all of our requirements. We started off with the community edition. Even though we were used to operating a billing system we quickly assumed, wrongly, ASTPP would not be for us and nearly gave up.

The migration was not plain sailing and that is not the fault of the product. The sheer determination from the ASTPP team to make this a success has been staggering and they have worked with us to ensure a positive outcome. We have been live for a few months now and honestly have not looked back. Due to the additional features available we opted for the Enterprise edition along with a support package.

Well done and thank you team ASTPP.

We use ASTPP as our softswitch and it’s been a solid platform for our needs. It strikes a good balance between billing and customer management, making it easy to run day-to-day operations without things getting overly complicated.

The ASTPP team is great to work with. Support is always responsive when we need it (which isn’t often), and they’re happy to help with custom changes, questions, or general guidance. Overall, it’s been a reliable solution backed by a helpful and approachable team.

Despite being a powerful tool, ASTPP isn't without its learning curve. The extensive feature set can be overwhelming at first, but its comprehensive document

“ASTPP by iNEXTRIX, an amazing journey”

Overall rating5.0
I started with them in the early 2020 and immediatly I understood their knowledge and appreciate their availability, that was important for us wanting to realize a great project. Till now, together we've realized a lot of personalized features and actually we're still working together to others. I searched a lot for someone that would be more than a supplier and I can say now that they are for us really partner. I dont know if there are better company and really I don't care of it because iNEXTRIX is the better for us. Trust in them and even you'll appreciate their power.
