I am using CMdaInputStream, CMdaOutputStream, RTP and SIP API's of S60 development kit to build a SIP Client for voice conversation.
Kindly guide me is it possible or not. Do I need any codec for compression of stream obtained from CMdaInputStream.
Using SIP Server provided with S60 development Kit, I am successful to transmit data to the remote client. But it took 20 seconds to receive 40K.
