Greetings I have been looking into different options for a phone system replacement. Currently I’m at the proof of concept stage. I have a few questions regarding 3cx and would like some recommendations. 1) I will likely go with SIP trunking. Does anyone have recommendation for a SIP trunker. For Mideast US (Indiana, Ohio, Michigan area) I found a few but they have minimums that don’t make much sense for a small system that will last a few months. 2) Looking for a recommended inexpensive handset for my proof of concept. One that is easy to get working with 3cx but costs less than $150. It will need to be dual port. 3) The 3cx brochure mentions fax support. However I read another forum posting stating the fax server was no longer support. Does 3cx still support incoming? 4) What is a recommend max latency between the handset and the server? Would 75ms be too much? 5) I have not downloaded the software yet, but I understand there is an option to trial the full version. How long is the trial? 6) Extension to extension; is that licensed as one or two calls? 7) Is 3cx supported on Windows Server 2008 R2? And will it work in Server Core mode. 8) Best way to prevent “hacking”/ exploiting poor security practices? I assume that preventing the use of softphones from the outside should help reduce the risks. With my proof of concept the design will only allow traffic to pass the firewall to and from my sip provider. Dealing with user laziness will be a challenge later. 9) Anyone have issues running 3CXbehind a SonicWall firewall? ( I miss my checkpoint) 10) Does it support on demand call recording? Or is it a record all and none? 11) Feature wise; Is there any difference between Mini, Small Buss, Enterprise? I know some of these questions could possibly be resolved if I had read all the documentation, but I’m being an n00b. Prior to actually installing the software I’ll it will get read. Right now I’m trying to feel out if 3cx is a good fit for me. One think I was drawn to was the fax server, just need it to receive faxes, read DID and email to the user. Thank you for your time.
