Hi there, I've just looked into 3CX and it seems to do everything i need. At the moment im just trying to put all the pieces of the puzzel together and could use with some help. I'll be running 3CX from a shuttle PC - which will always be on, and only used for that. The phones i'll be using are the linksys SPA921 models - 4 will be connected via ethernet, 6 via wireless pack (linksys WBP54g). Im trying to also have a backup PSTN system should my broadband connection fail. And for that im thinking about using the linksys SPA3102. As far as i know of the handsets and the analoge adaptor should work fine with 3CX (as its said on the webpage) - i'd be greatful if someone could confirm this to me. But the problem now is finding a VOIP provider that can meet my needs and work with 3CX! I live in the UK - and most of my calls will be made to the UK (landline and mobile), Dubai (landline and mobile), Iraq (landline). I need to keep my existing UK landline number from BT. At the moment the only provider i can find is Vonage, but i dont know it it will work with everything above, and the call cost is expensive on them. Does anyone know of any other provider which can work, and provide me with call lower costs? Also if this setup is successful, i need to roll out another UK VOIP system and a VOIP in Dubai - what would be the best way to go about this - i.e. free calls between each other? -------------------------- Edit: My existing network setup is : Cable modem > wireless router > Hub > Wireless AP & ethernet points Planned setup after: Cable modem > wireless router > Hub & SPA3102 > Wireless AP & ethernet points & telephones Will this work ok? thanks for the help.
