VoIP Softswitch with integrated call generator, filter for VoIP wholesale, IVR, looped VoIP traffic and various complex VoIP applications
The software is a Windows-based VoIP softswitch with integrated routing, billing, filtering (fast numbers lookup) and web interface.
It can be used for VoIP wholesale carriers.
Advanced call processing in the softswitch is based on CallXML scripts and integrated routing/billing engine.
The softswitch is able to recognize speech (voice) to text using VOSK speech recognition server (based on Kaldi).
The softswitch is a continuously-self-tested system with high stability and performance. We invest efforts into software development and testing, not marketing and web design to keep low prices.
Structure of database is clean and simple.
SIP and RTP modules (same as in SIP Tester software) are used by more than 800 customers all over the world.
Key features
- Voice-based IVR: recognize speech to text (STT) using VOSK speech recognition server (based on Kaldi).
- Features for generated VoIP traffic: dialer campaigns, looped generated traffic. See step-by-step tutorial
- High-performance scalable dialing based on custom CallXML scripts (complex call scenarios)
- CLI manilupation (replace with numbers from CSV file)

Reviews
Startrinity is a highly reliable Softswitch which offers major benefits with a professional support team.
Its routing & billing all-in-one functionality is very efficient and works seamlessly.
We would definitely recommend it to any start-up & existing business in the wholesale telecom field.
Eyal Astanglov, CTO at Vocalix Ltd
I have been in the business for 21 years I worked with many switches and helped in building some, however this startrinity switch
have proven to be one of the most solid switch if not the best when it comes to core operations.
It still lacks some functionalities however the owner is working hard to add all needed functions,
not only he is brilliant but very dedicated and has an excellent customer service.
I would recommend and encourage anyone who is looking for a solid switch.
Not to talk about his SIP tester that is been used with one of biggest providers in Canada.
All what I can say, it is simply the best and we should encourge and support such a wonderful work.
Thank you for all the hard work and keep up the good work.

StarTrinity Softswitch would have to be one of the best products I have ever used, the ease of using the CallXML scripting language to deliver the requirements we had to deliver an automated solution to our customers, I would highly recommend this product to anyone exploring.
Steven Sinfield, Australia, Soul Path Psychics
After very long research of VOIP softswitches and trying most of them we found StarTrinity. It has all features we need surprisingly.
Thus its developers are very helpful and they welcomed us. Thank you for your all effort, great job!

business too.
Customer #19 from Asia has successfully started VoIP wholesale business with our softswitch. He is trading NCLI routes to Africa,
has direct connections with GSM gateway owners (direct routes). The customer helps us with suggestions for development of softswitch, requesting new features and designing new screens
Customer #24 is using the softswitch for retail VoIP origination business in Canada. The VoIP traffic is originated from mobile SIP client or from DID number from Canada
to a country in Middle East. Invoices are managed manually via softswitch web interface. We are planning to develop our own mobile dialer app (in 2017)
