not technically a question but i get really pissed off when people say that it is impossible to call people or text on the itouch for both of these things you need a jailbroken itouch
for texting
go to installer then go to sources and click edit then add and then add the source: twenty08.com/installer then install the chatting program sign in to the program and click "new im" if you are in the U.S. add +1 then the area code and the number type your text and then you're done! (your friend can reply to this message)
to call
add the source: touchmods.net/rep.xml then install the sip-voip application then go to voipcheap.com and download their program open the program and make a username and password then open the sip-voip program and type in your username and password and where it asks you for your server type: sip.voipcheap.com then you should be done (at this point you can only call people, you cannot recieve calls and you cannot speak) to speak you must purchase an itouch mic

SIP is the signalling protocol for most VOIP applications today.

I was wondering if anybody knew of any good SIP (session initiation protocol) simulators , i have tried it on OPNET and OMNET ++ , but if you guys know any new open source simulators or discrete event emulators , it would help a lot ..

thnx in advance

Anyone knows how to set up a general voip website for people to use? Are there any open source software out there?
What are the costs from my end?

I am also in need of SIP client program can run on PPC ...
The SIP server I need is just used for manage the sessions and transactions, there is no need to do anything with Voip.

Any suggestion for me? Thanks!

The OS Android utilizing the 3G network, T-Mobile requiring you to go with the unlimited data plan if you have the phone. With the OS being open source, what is preventing someone from developing an application that would utilize a VoIP service and the unlimited 3G network bandwidth to allow for unlimited minutes?

(My guess is that because the coding is in Java, and Java doesn't have the power to create such an application. Anyone else care to explain if I'm correct in this?)

i want to contribute in open source project. My interest area are network security, voip security, web security or finance domain (FIX protocol for example). Can anybody guide me how to conritbute? I know of sourceforge and freashmeat but not very clear about the status of project listed, popularity etc.

Like a wiki, VOIP, Chat and blog.
If so how is it done (what codes do you use...ajax? css?) and how long does it take to code it.
I'm currently doing a project about this and need to find out more in-depth info.
