Thanks for your reply Nanang. I had doubt about the CPU load issue but so far decoding was working smoothly I thought there might be other issues that I might have missed. As I had a miss conception that encoding and decoding will use similar amount of CPU load, finally I'v understood, decoding takes far less CPU utilization then encoding hence it was working fine. I don't have any clue where can I get more optimized g723 codec for ARM processors and optimizing the ITU codec is beyond my understanding of the code. After going through some of the codecs datasheets it says for G.723.1 it takes approximatly: Encoder 5 1/3k bps requires 18 MIPS Encoder 6.4k bps requires 26 MIPS Decoder (5 1/3k bps or 6.4k bps) requires 2 MIPS where G.729 Annex A Encoder/Decoder requires 10.8 MIPS will it be suitable to use the ITU code for G.729 with pjsip-symbian ??
