Our Story

While every aspect of our lives are changing, from social to econimcal, we are all apart of the same transition. While spending over two decades imrpoving managed telecom solutions, many problems in the industry were identified that continue to persist without real solutions. SIPSTACK was founded to begin solving some of these problems by creating a unified management platform for Asterisk that is elastic by nature, and could scale and adapt while maintaining a single point of administration and access. This has become Cloud UC, the PBX management tool every carrier and provider has been waiting for. Although efforts have been made to stop fraudulent calls with technology, it is a 55 billion dollar industry in the US alone.

Our Mission

Our products are designed with two purposes, first to provide next generation experiences and services to the telecommunications industry, and secondly to eradicate fraudulent and spam calling, period. By driving authentic data through our AI/ML models, community feedback and various other data collection methods, we are able to provide hyper-accurate call ratings that are dynamic to the recipient of the call. While our efforts are only in the beginning stages, we will be targeting this epidemic from all levels and angles to end this era of fraud for good.

Dedicated Team

Our Company Values

We are human

Deploy one or many hosts to serve multiple PBX from a single branded management web portal.

We are AI responsible

Processing big, very big data at a global scale requires strong fundamental values instilled at the very core. Securing and maintaining privacy is at the forefront of every founding block of AI code we commit.

We are forward thinkers

The challenges we face today in telecommunications will continue to evolve. Solutions should not be short term designed, technology should continually adapt, outpacing bad actors. While our products and services advance, so do our capabilities in ending telecom fraud.

We are creative

Challenges are dynamic, and solutions are not static. Developing new products that are attractive , effective and compliment new learning streams into our AI applications take a whole lot of creativity and fun.
