Performance

We have run performance tests with the softswitch on various dedicated servers in order to get servers' call capacity for stable performance, here are results:
Dedicated server, Windows Server 2012 R2 64bit, 4x3.4GHz CPU, 8GB RAM
  • Typical CC traffic, no recording to WAV: ASR = 70%, ACD = 20 seconds, codec = G.729, 70 calls per second: 1300 channels (version 2017-10-09)
  • Typical NCLI traffic, no recording to WAV: ASR = 40%, ACD = 4 minutes, codec = G.729, 14 calls per second: 1200 channels (version 2017-10-09)
VoIP quality indicators (RTP jitter, packet loss, MOS score) have been measured during the tests; the indicators have been OK during the 48-hour load tests.

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.
