Hi, I am trying to use the ITU G723.1 codec in pjsip, so far I it is working perfect and voice is clear for windows, using the pjsua_vc.exe. When I was trying to use the same codec for symbian_ua_gui it was not giving the same expected result. I have tried to debug this and found that in symbian some how the problem is in the encode() function and when the encode function is enabled the decoder function is never called. when I tried with disableing the encode() function then the decoder function is working smoothly and I can hear the voice from the symbian_ua_gui of the other party. I am attaching the g723.c file please check if i am wrong in any place. Symbian 9.1 3rd ed Not using the aps Phone E65 , N95 best regards, Aftad -------------- next part -------------- An HTML attachment was scrubbed...
