Hello, Have you always had the problem using wengophone or is it only recently ?
Have you tried another codec like G711 (pcmu for instance) ? it could help locate the problem more easily because g711 is somewhat simpler than GSM.

Hello, My platform use OSS sound device (with 8000Hz, 16bit, 1 channel). I make a call from my platform to PC (Xlite Softphone). I used GSM codec. The PC hear the voice quickly. But my platform hear the voice with delay 3 seconds. I use Ethereal on PC can see the Audio packets (inside RTP packets) was sent with correctly timestamp. I already disabled: AEC, VAD/CNG. > From Vadim. >do you ALWAYS get the delay? I always get the delay. >Is the delay growing during communication? The delay does not growing during the communication. I can hear the voice well but it all voice packets was delayed 3 seconds. Thanks for your advice.
