Hi, I am using PJSIP. I am experiencing the following problem. When I make a call I can hear the recipient clearly without any problem at all. However the recipient of the call cannot hear me clearly. Voice breaks every few seconds. So for example if I say the the following: ?"Once upon a time there was a little girl who went to school" the recipient will here "Once upon ...... time there....... to school"?The ...... depicts loss of audio. I have made over 30 test calls from 3 different Android devices using both Wifi and standard 3g data. The result is always the same. I am using the following settings: Echo cancellation (Active)Clock Rate (Auto)Media Thread Count 2Codec priority list per bandwidth is active:Codecs - FAST ?PCMU 8kHz, PCMA 8kHz, SILK 24 kHzCodecs - SLOW SILK 8KHZ, GSM 8kHz, PCMU 8kHz, PCMA 8kHz Please can somebody help and tell me how to configure things properly? Thanks in advance. GQ -------------- next part -------------- An HTML attachment was scrubbed...
