Re: SIPping from the VOIP fountain

Once a call has been connected, all VOIP systems have a similar way of pushing voice through to the other side which is pretty much -> take a piece, wrap it up in as small an envelope as possible and push it through as fast as possible.

If pieces get lost then the other side will just play silence or white noise for that split second.

Since this part of the communication is has to be very quick - there is very little security involved.

Where different systems differentiate themselves form each other is in the part where a new client is added to the network and when two clients establish a session (call).

Skype has their own propriety way of adding clients and setting up calls whereas Gizmo and the like use SIP. Most VIOP phones, such as Cisco's phones et al, use the SIP open standard.

Since SIP is an open standard there are a lot of different "tools" that use it such as VOIP Cell phones, softphones such as the XPhone, VOIP phones such as Cisco's IP phones, online VOIP services such as Gizmo, open source PABXs such as Asterisk, etc.

Putting all of these technologies together can be quite fun. (And because SIP is open and very widely supported they CAN be put together) which means you could for example:

1. Get someone to phone a number (here or in the US or another country) which is then converted to IP,

2. It gets routed to a "switch" box which knows if you are in the office or not.

3. If you are in the office then the call gets routed to the desk that you happen to have logged on to or to a softphone on your PC.

4. If you don't pick up in time then the call gets routed via wireless to your cell phone.

5. If you still don't pick up then the system guesses that you are out of the office and routes the call to your cell phone via the Internet

6. If you still don't pick up then it gets routed to your cell phone number,

7. If you still don't answer then the call gets routed back to your PABX where a person has the option to leave voice mail.

8. If you are out of the office then the call doesn't get routed to your desk phone or via wireless - it just goes straight to your cell phone via the internet.

There are about 5 different "products/services/tools" in action while this is happening and since they all talk SIP - they can all work together.

This is why SIP is so powerful and useful.

I think that you are being a bit harsh on Nokia considering that this is Beta software and was released yesterday.

The fact that this is being done on QT software is a good step in the right direction and shows that there is at least an intention to port this across to other platforms.

The most difficult part of this will be to get drivers to work properly and I bet that Nokia are working on that. The package doesn't even work properly on Windows because it can't use a proxy so its still early days.

What would be amazing is if they open the source to the Ovi App. Or at the very least open the API so new applications can be written that "plug into" Ovi. And, at the same time the application can be ported to Apple and Linux.

I think this is just an exercise in "I am not a Nokia fan-boy"

Shame on you...now hand over your N97..

Death threats?!

You'd better eat that burger quickly! Then you don't have to worry about dying.
