Hi, Omkar Here. I have installed 3cx pbx phone system on win server 2012 R2, activated it and able to access its web interface. Also I have installed the 3cx phone on a client machine and the server also. I have few queries regarding the whole setup which r listed below: 1. After installing 3cx phone on the machine, it is showing some message "3cx phone for 3cx phone system 12 has been installed. No phone system configuration detected. Double click on the attachment in your extension welcome mail or drag and drop the configuration to 3cx phone. 3cx phone requires 3cx phone system version 12." I have not received any attachment in any welcome mail. Infact I just got a mail from sales team. Please help me in what is this message all about and what i need to do further? 2. I want to run this system locally for testing purpose and for this what will be the configuration in server and client? 3. Is this 3cx phone system having creating multiple organisation feautre? I saw this feature in Elastix PBX server. 4. Is there any Instant messaging feature in it for chat? Kindly help me out in this regard. Thank you in advance.
