by the way will i need any special pci card for me to conect the ip phone with the pc ill be running the pbx software or switch that all the phone will connect to it?

but then that depends on the phones you use. If you use PoE phones, then you need a PoE switch. If you use phones with power bricks, then just a basic 10/100 switch will work.

don't forget the cost of FXO and FXS modules you'll need for foreign and local POTS connections [they aren't cheap].

and check to make sure the software you have allows for the # of users you have.

istn there a simpler way by using normal voice modem wich will support nomal ip phones or others.i tink using the basic 10/100 switch is more cheaper but is the phones with power bricks available on the market and is there any pbx software for window that is compatible with this system?

You need the modules that CG IT says. Regular voice modems will not work.

VoIP is a lot more complicated than your envisioning...

modules [FXO is foreign exchange] and FXS is for POTS [plain old telephone system]. These are the interfaces [does the packet massaging] between your VoIP and regular phone lines [POTS]

Also don't forget the gateway. Typically using H323. A server can fill this role or you can use a router that supports H323.

Not sure about a Windows based PBX system. I only know Cisco stuff and then just enough to make a mess of it.

Ah a little web search and here's a Windows based PBX system.
