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.

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.
