I am a beginner to VOIP on S60 and in general also . Actually we have developed an application for S60 3rd FP1 which takes the sound input from mic using APS and send this voice over the CSD line. On the other hand we receive data from data line and play it on earpiece using APS. This is nearly working perfectly. Now the main issue is that we want to replace the CSD line with VOIP because of non availability of CSD in every network/country. So i have few concerns about it as i still do not know from where to start and how.
1. Is it possible to use VOIP instead of DataLine for transferring Encrypted voice data? If yes then how any pointers please.
2. I want to know how to utilize VOIP for my need so please give some starters.
3. I have used APS for recording and playing and understand its uses but still unable to know how data transferring can be done through VOIP.
Thanks & Regards
