voice over ip [modified]

we are agroup in agraduation project want to do an application to make calls to mobile phones using voip . do we need anecessary network device or asoftware for segmenting voice packages? -- modified at 22:18 Sunday 4th November, 2007
You will need a call control stack to do the call setup and tear-down and then a voice (RTP) stack to send a receive audio. I would suggest using SIP for the call control stuff since is is a more popular standard that H.323 used to be and is more widely used now by most vendors. Depending on what your host platform target is you might want to consider trying the Microsoft Real Time Communication (RTC) API. http://technet.microsoft.com/en-us/library/bb457036.aspx[^]

His instructor shouldn't have a monopoly over his knowledge. Anyone can learn from any source. You might say he could be trying to cheat, he is suppose to figure this out on his own. Well he is figuring this out on his own, he is using the internet to gain valuable information that he needs. It doesn't make any difference where he gets his information.

I agree. Use it as a powerful research tool, but not for cheating (which I have not implied that he is doing).

If you are going to attack someone in an open forum (and Kyle has needed attacking form time to time - don't get me wrong there) the at least have the cajones to do it openly and take 'credit' for it... Interesting way to post a message though... Might make a neat add-in for IE :)

If you are doing pure VoIP then all you need is your network interface. The only time you really need 'things' is when you want to cross domains into the TDM (circuit switched world) like the PSTN. Then you need gateways (what I do for a living). Other times might be if you need to change call control protocols (conversion gateways) or change voice protocols (transcoding gateways) or things like that.

The disclaimer makes people more curious and more likely to try and figure out what it says. If I didn't have any balls I wouldn't have used it as my sig. I knew that I would get shit over it but oh well, I'm not going to submit to everyone else and act all nice and not use profanity and shit because thats just who I am, a fowl mouth ill tempered 20 year old. If you don't like me, then don't talk to me.

When someone says "Fuck you" they are telling you to go fuck yourself. Your delusional thoughts about me being a homosexual and your admirer is absolute garbage.
