What kind of g729 you are using? It depends on that. try speex/gsm that is already there with gui.. and compare the quality with g729 you added.

Hi Rawshan Iajdani, Thank you very much for your reply. I successfully added G729 with symbian_ua_gui. Also I can call with G729 codec. But there is some problem with sound quality ( cracking sound and bit noisy ). That is why I thought about ptime of symbian_ua.cpp . So how can I overcome from that problem ?

Nasir Uddin Sent: Saturday, November 15, 2008 7:24 PM To: pjsip at lists.pjsip.org Subject: Ptime... Hi All, I am trying to add G729 codec in PJSIP ( symbian_ua_gui ) for Mobile. I found in symbian_ua.cpp med_cfg.thread_cnt = 0; // Disable threading on Symbian med_cfg.has_ioqueue = PJ_FALSE; med_cfg.clock_rate = 8000; med_cfg.audio_frame_ptime = 40; med_cfg.ec_tail_len = 0; med_cfg.enable_ice = USE_ICE; med_cfg.snd_auto_close_time = 5; // wait for 5 seconds idle before sound dev get auto-closed But "med_cfg.audio_frame_ptime = 40" is not clear to me. Does this ptime affect ptime of G729 codec.
