I am a new user to the 3CX phone system software. I am trying to setup the Linksys SPA 3102 after upgrading the firmware. I went thru the process of configuring the PSTN gateway as 3CX gives it here: http: //www.3cx.com/voip-gateways/linksys-3102/ - NO LONGER AVAILABLE. I ended up with the line status, "Not Registered" under the tab, "Ports/Trunck Status" in the 3CX software. I then realized, although not sure, that the easier way would have been to use the procedure for "provisioning" the SPA 3102. After studying about this, I saved the configuration file (XML) generated from 3CX in the folder "C:\temp" and used the string "http://192.168.1.104/temp/linksys-spa-3102.gwcfg" in the "provisioning" tab of the gateway setup webpages (see attached linksys-spa-3102.gwcfg). The IP of the computer running the 3CX software is 192.168.1.104 and is where the configuration XML file resides, whereas the gateway is 192.168.1.100. Below I have attached a few files for someone to figure out what I am doing wrong.
