So what you are saying is that Skype is not willing to offer the application for Blackberry ? i am unable to understand the rational behind it as the same application is available on other hand held device.

Blackberry does support SIP connections to Cisco Call Manager Client as far as i remember but other than that i guess RIM haven't provided any API or low level access to developers for SIP programing. I've used thin Skype on BB but it uses a tie line feature and make calls to local numbers to connect to voice which is not VOIP obviously.

thnx.

Hi rahuljaiswal07, I tried sip-for-me stack, and also the mjsip, actually they work pretty well on BB, and only some little adjustments need to be made on the connection socket, adding some arguments like deviceside=true;interface=wifi, however, don't worry to get sip working, because what said aviator is true, you cant record and play at the same time, the problem is that the implementation of player is managed by system threads and is not accessible for us to manage, I've made a simple app, that starts a thread and plays a sound in loops, that works fine, also, I can start a thread to record, that works fine to, but if I start the recording thread and the playing thread both players stop, they don't play or record, that was tested on the simulator and on the javelin 8900 actual device.

So to make it clear, JavaME, in the JSR135, don't specify that the players should record and play at the same time, BB just don't support such feature through JavaME, you would need more low level access than java provides to implement a VoIP app on BB.
My advice, either don't try it at all (and don't waste your time, go for android ), or go to talk RIM directly (if you have the budget to do so).
