Hi. I'm really new. I was just wondering if it is possible at all to do a IP to IP call without a * server (or as a matter of fact, any other kind of server)? say I'm at mydomain.com's 10.0.0.1 and I want to call my buddy at hisdomain.com's 192.168.0.3. Is this sort of things possible? Or must we all both be registered with the same server to do that? Can this not be done without passing thru server (*)? Thanks.

Technically speaking, most VoIP protocols are peer-to-peer; as long as both ends are using the same protocol, any call can ultimately be a direct connection between endpoints. If you can configure the dialplan in your terminal (IP phone or soft client) to know exactly the IP address of the destination endpoint (your buddy's IP phone or soft client), and the destination endpoint is willing to accept incoming connections from your client, you're good to go. Getting this going across networks is usually a bit more complicated that that. ~~ No: ~~ Being "really new", you'd avoid a ton of frustration for yourself (not to mention a steep learning curve) if you interface through some sort of registration server. Why create needless hassle for yourself? When you start adding firewalls, NATs, DHCP, mobility and a bunch of other things, it becomes attractive to centralize these configurations in a machine that provides lookup services to all users. It's not *needed*, but it is very beneficial. Ultimately, the complexity of the network is such that it will become a necessity. For example, the internet works fine without DNS (some apps do not, but I digress), but without it, everyone would need to keep track of IP addresses. DNS has become essential. Similarly, there is no technical reason to have Google, but can you imagine surfing without it? If you want to use VoIP without getting into Asterisk, services such as FreeWorldDialup are worth looking into. Cheers, Jim.

[Asterisk-Users] IP to IP call without server?
I agree you can do this with SIP. but I would use skype, msn, yahoo or VOIP blasters (get on ebay) for a simple call to call without a server. its too much effort and too much to learn for a simple call.

Is this sort of things possible?I think this kind of functionality is supported by some SIP phones. Well the docs of my budgetone says it does, but I've never tried it.> Or must we all both be registered with the same server to do that?

I also think SIP has a similar mechanism (REINVITE?) - but then again I'm fairly new to VoIP so I might be talking all rubbish. If I am please someone correct me :-) Cheers, Jean-Michel.
