In the wake of Hurricane Ernesto, Puerto Rico faced significant disruptions, particularly in healthcare services. Hospitals and clinics had to act quickly to inform hundreds of patients about changes to their medical appointments. In such a critical moment, SIP Caller played a crucial role in ensuring that communication was swift and efficient.
In critical moments, technology makes a difference. During the recent passage of Hurricane Ernesto through Puerto Rico, Quantum faced the challenge of canceling and rescheduling essential medical services in record time. Thanks to the predictive power of the SIP Caller dialer, we were able to contact more than 600 patients in less than 48 hours, managing the cancellation and rescheduling of appointments in an individualized, precise and timely manner. This significantly reduced the risk of exposure to the atmospheric phenomenon for patients and ensured effective communication in logistics management. Without a doubt, this is a tool that we will implement in our standard communications operations.

Our customer leveraged SIP Caller’s advanced dialer technology to reach out to hundreds of patients in a matter of hours. With the ability to send personalized messages and automate follow-ups, they were able to manage the situation effectively, minimizing confusion and ensuring that patients were well-informed.
We are deeply honored that SIP Caller could contribute during such a critical time. Our mission has always been to provide reliable and efficient communication tools, and it’s moments like these that truly validate our work. We are proud to support our customers in any way we can, especially when it involves helping people during emergencies. Putting our technology at the disposal of those who need it most is what drives us every day.

A regional Google Cloud outage caused by a power event took our London infrastructure offline today, and campaigns in the Europe - United Kingdom (London) region stopped making calls. The issue is now fully resolved. We explain what happened, apologize for the interruption, and show how to switch your phone system to the next nearest region, such as Milan, so your campaigns keep calling if it ever happens again.

The past few weeks have been an exciting journey for the SIP Caller team as we traveled across Europe to meet with distributors, partners, and industry professionals. While video calls have become part of everyday business, nothing replaces the value of meeting face-to-face, exchanging ideas, and discussing the future together. Our tour took us to three incredible destinations, each reinforcing the importance of collaboration and the strong partner network that continues to drive SIP Caller forward.

This July, the SIP Caller team will embark on an exciting journey across Europe, meeting with distributors, partners, and industry professionals while sharing the latest developments in our platform. As SIP Caller continues to expand globally, these face-to-face meetings are an invaluable opportunity to strengthen relationships, exchange ideas, and discuss the future of outbound communications, automation, and customer engagement.
