I know lots of people have already asked about the config of the Linksys SPA3102. However I have some questions about how to physically attach the SPA3102 box to our network for use with 3CX. We would like to use 3CX for remote workers, we already an Alcatel phone system and would to connect the SPA3102 to a spare analogue extension which we can then use to make and receive calls via 3CX. My questions are which ports should I use on the SPA3102: Ethernet, Internet or both? Which instructions from: http: //www.3cx.com/voip-gateways/linksys-3102/ - NO LONGER AVAILABLE should I use, do I need to configure the 3102 as a VoIP gateway or an ATA? Thanks in advance.
