Just two questions: How can I changethe port of the web server? Lots of options in the admin panel, but nothing for something THAT basic. I want it to run on port 80 for simplicity. What is the timeframe for CSTA / Office Communication Server 2007 integration? We are just setting up a new infrastructure for the offices, and I would rather sleect a standards compliant CSTA supporting PBX, so that we can unify our employee infrastructure on Office Communication Server. The integration of chat, presence information, videoconferencing with the functionality of a "slaved" pbx that our employees can control from office commmunicator (meaning they only need one program installed, and that i can make cheap phone calls from my mobile phone using the pbx at the office) just is too good. In fact, "no plans for providing SIP over TCP and CSTA" is a delbreaker for the usage of 3cx for me. So, what is the status on that? Any plans for an "enterprise" version that supports clustering? Naturally uptime is limited for a single system. So far it looks like the only way to get enterprise level uptime is by running 3cx in a virtual machine (and cluster this, so that it restarts on a different virtual server when the hosting machine fails). I would like to know how the scenarios look for clustering support in 3cx for multiple installed pbx's to work together.
