Hi:
I am thinking of creating a "dedicated personal VoIP network" to connect my parent's home phone (in India) with mine in Canada. I have a very little knowledge about the VoIP technology, but after a brief research, my undersatnding about the architechture of the VoIP is as below:
Phone(POTS)+---+PC+---+Gateway+---------+(Internet)+---------+Gateway
+---+PC+---+Phone(POTS) | | | | | Line+-----------------
+
+------------------+Line
To install the system, I may need following components in both locations:
1) Each PC (Windows XP) at both locations should have: a) Network card connected to internet services; b) Gatekeeper and Call Processing software been installed and running; c) Phone line from wall is connected to the RJ11 port (line); d) Phone is connected to the RJ11 port (phone);
2) Each Gateway (either PCI card or modem like box) connected to the PC at one side and other to the internet (either through modem or home network router).
Now, I have questions and need your suggestions:
1) What Gatekeeper and Call Processing software should I use ? (I prefer open source and free).
2) Where can I buy a good "Gateway" (PCI card or modem like box) ?
3) Do I need any management software installed in the PC (for configuration) ?
