I work from home and have 2 x analogue phones (on different numbers) & a cable broadband. "Office" side of things has cable broadband, an MS Small Business Server & a web server. Cabling is 100mbps and wifi. What I'd like to do is:- 1) Use 3cx 2) have the "system" answer either of the pstn lines and route to the appropriate hanset (ie business to business, & private to private) but be able to transfer the call between handsets. 3) Allow any handset to dial out over VOIP 4) Accept incoming VOIP calls (not essential) 5) Voicemail & some kind of integration with the Exchange side of the SBS - not sure what but it's shiny & I want it I'm confused as to what hardware I need - can someone help? The more I read the more the FXO/FXS thing confuses me. I'm happy to replace the existing alanlogue phones with IP ones.
