Hi, I am setting up 3cx at home to connect my family that is living in different parts of the city. The objective of setting up 3cx was to have 4 extensions in the house, and 3 remote extensions, one at each siblings home. I've installed 3cx successfully on a pc running on Windows XP. the hardware config is P3, 256mb Ram, 40Gb HDD. This machine will be dedicated to 3cx. I have Linksys WRT54G router and Linksys SPA3102 for connecting my VOIP phone and PSTN phone to 3CX. Currently I have 2 Dlink C160s VOIP DECT Cordless phones, one of which I am planing to use for testing as a remote extension. All remote destinations, including my house have ADSL connections with 512kb bandwidth. None of us have static ip from our ISPs. I am looking for some help and advise on how to effectively setup remote extensions. I am a bit confused on 3cx requirements for * STUN server, * Static IP (using services like DynDNS) * Port forwarding. I would appreciate if I can draw upon your expertise to understand if I use all 3 or only a combination of 2? Which ones and how? Please note that I am not a techie but am just fascinated by the possibilities of VOIP. Thanks.
