Hi,
I want a program that, given my IP address and another person's IP address, will let us converse with sound i.e. make a VOIP call. I'd prefer that no 3rd system (server) be involved. We are both using wireless routers.
Is this possible? Is there a program that will allow it?
If a 3rd system must be involved, is there a simple PHP script that could coordinate making the connection?
Thanks.
This is typically referred to as click to call functionality
If you have a big volume of calls you need to centrally initiate, drop me a call and I can share some ideas with you.
How about SpeakFreely?
It's about as basic as VoIP gets, but you can talk, and even use encryption if you want to.

If your OS is windows, I suggest you to try miniSipServer and Xten.
miniSipServer is a kind of SIP server and Xten is a kind of SIP client. You can use them to establish your own VOIP network.

Any VoIP Program using the SIP protocol is able to do this. The problem is NAT, which is probably made by your router.
You will have to open a port, normally 5060, for the signalling of incoming calls to your PC or phone device.
I prefer SJphone which is freely available for lots of systems.
If you know the IP the only 3rd system necessary is a STUN server which just helps to hold the route open over the NAT.
Then just "dial" the IP-number and it is done. Even commercially available IP-Phones based on the SIP protocol are able to do this. So you even do not need a PC.
