As 3CX recently announced, users still running version 18 must migrate to version 20 to continue accessing critical support services, including the 3CX forum and free support. This migration is crucial, but it comes with potential challenges for those utilizing Call Flow Designer (CFD) dialers.
If you're using a CFD-built dialer in 3CX v18, be aware that upgrading to v20 may affect your current instances. In some cases, users will need to make significant changes to get their CFD dialers to function properly. If this is your case and didn’t upgrade to v20 yet, ensure that you take some time to verify how your app works in v20 before upgrading.
Here’s where SIP Caller comes in as the ideal solution. Our product is fully compatible with 3CX v20, ensuring that you won’t experience any disruptions in your outbound calling campaigns when you upgrade. SIP Caller works effortlessly, providing a smooth migration path.
But compatibility is just the beginning. SIP Caller offers a wide range of additional benefits that make managing and scaling your call campaigns easier than ever:
If you’re planning to migrate from 3CX v18 to v20 and you’re using a CFD dialer, it’s time to consider SIP Caller. By doing so, you’ll have a user-friendly solution that enhances your call campaign management, improving your overall 3CX experience.

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.
