At AstriCon, Xorcom
today released a new hybrid (VoIP + PSTN) telephony solution called the CXE4000 featuring Xorcom's CompletePBX distro (based on Asterisk and FreePBX). The CXE4000
is a heavy-duty, stand-alone, pre-configured, out-of-the-box IP PBX It is optimized for businesses with extremely high call volumes and / or additional communication applications.
At the last ITEXPO in Las Vegas I spoke with Xorcom's Ruth Bridger who talked about their CompletePBX solution, which is based on Asterisk and FreePBX with Xorcom's secret sauce added in. I recall her mentioning how they use USB to add scalability and redundancy to their product line. Indeed, the new CXE4000 supports various combinations of telephony ports via Astribank units connected via USB2: up to 960 PSTN/analog phones ports, up to 24 E1 R2 / T1 CAS PRI ports, up to 1500 users and up to 750 concurrent calls.
