[slide346] So for example, in contact parameters, you have a class parameter. Is this a personal call or a business call? And that might be important for billing. So is it billed to my business account, or is it billed to my personal account? Is it full duplex, half duplex, send only, or perhaps receive only? Now why would you have a receive only call? Well, if you look at lots of businesses, they have quarterly announcements, right? Here's how business is done in the last quarter. If you're a stockholder in the company, or maybe you're a broker specializing the company, you would listen to that presentation. You're not going to say anything, but you're going to listen to it. So you might actually specify that you want only a receive only participation in that particular session. Or you might be send only. The other party might only be sending data out. They're not accepting any media in the reverse direction. You can look at features like, I actually don't want to talk to the person. I want to leave a voicemail message for them, because I don't really need to talk to them, but I need to communicate this information with them. So I can specify, don't bother the person. Go directly to his or her voicemail. I can specify a language. In this case, I could say, I would like it in English, German, or Swedish, but not Finnish. So the result is the callee can direct the call now based upon the language abilities of the staff, so that in fact, I reach a person that I can communicate with. MIME types. We can include all kinds of different information, including HTML, images, videos, et cetera, as recorded content. And we can say, I want to reach the user at a fixed location or their mobile phone, and a priority. Is it urgent? Is it emergency? Non-urgent? And I can even talk to a particular service. So if I actually want to talk to the user, I want to talk to the user's fax machine, because I want to send them fax content. Or I want to only send them to an IP service, et cetera. So there are lots of different parameters.
