ICTPBX is a robust open-source PBX platform designed specifically for Internet Service Providers (ISPs), Internet Telephony Service Providers (ITSPs), and various service providers. It integrates FreeSWITCH 1.10 as its core media engine with FusionPBX 6.6 for configuration, all streamlined via the ICTCore REST API and operated from an intuitive Angular 13 web dashboard. In contrast to hosted PBX options, ICTPBX operates fully on your infrastructure, giving you complete control over your data, tenants, and billing processes. Its scalable architecture allows you to expand from just a few extensions to thousands of users without incurring per-user licensing fees, making it a cost-effective solution. The platform is specifically designed for multi-tenant environments, ensuring that each tenant has their own dedicated PBX setup with personalized branding, quota limits, and role-based access controls to enhance security and customization. Key features include support for SIP extensions, ring groups, call queues (ACD), and interactive voice response (IVR) menus, along with voicemail, conferencing, time conditions, and complex call flows. It also supports SIP trunks (gateways), inbound Direct Inward Dialing (DID) routing, and call blocking for enhanced functionality. Furthermore, the system accommodates multiple tenants with individualized branding and quota management, while also integrating voice, fax (T.38/FoIP), SMS (SMPP), and email services into a single platform for streamlined communication. Overall, ICTPBX offers a comprehensive solution that meets the diverse needs of modern telecommunications.

R.E. Communications provides an IP-PBX system powered by Asterisk, compatible with all standard SIP phones and equipped with high-level features suitable for environments ranging from just 1 phone to as many as 4000. Additionally, these systems facilitate SIP trunking, allowing users to mimic the functionalities of a hosted solution while significantly reducing costs per seat. For instance, a system designed for 10 phones can efficiently operate with only 4 to 6 SIP trunks, resulting in notable savings compared to the expense of a hosted solution for the same number of seats. This versatility makes R.E. Communications’ offerings particularly appealing for businesses looking to optimize their communication infrastructure while managing expenses effectively.
