Hi, When making a call, via sip the caller can hear the other party but the other party can't hear the caller clearly. The voice is constantly breaking. The result is the same from wifi and data. I am calling a mobile number from my PJSIP VOIP app. My media settings are following, 1) Clock rate is set to Auto 2) I have selected 2 Fast Codec's PCMU 8kHz and PCMA 8 KHz. For Slow, i have selected SILK 8 khz, GSM 8 KHZ, PCMU 8KHZ and PCMA 8KHZ Please help. Thanks and Regards, Sharad -------------- next part -------------- An HTML attachment was scrubbed...
