Hello,I am continue investigating this issue. I found that for payload_type_pcm8000 MS_RTP_SEND has increased a frequensy of the packets. It uses 10ms interval instead of 20ms interval for ulaw payload. So it gives right quantity of 16-bit samples per second in 100 packets by 80 samples. But I need to have 50 packets by 160 samples, how can I tune this parameter?Best regards,Igor2017-12-20 12:32 GMT+03:00 Igor Chetverovod <address@hidden>:Hello,I am tring to build generator of tonal signal based on Mediastrimer2 filters. I am using chain of filters:MS_TICKER -> MS_VOID_SOURCE -> MS_DTMF_GEN -> MS_VOLUME -> MS_RTP_SENDThis chain works good when I connect in to the saundcard. But when I use RTP-session with payload payload_type_pcm8000 (clock rate 8000 , bits per sample 16) I see in output RTP-packets only 160bytes of payload not 320. Could you please clarify how to get solve this issue?Best regards,Igor
