Hello list, a long time ago i have build and application which injects ringing from rtpproxy to the client, while i am trying to reach his destination. The commande looks like this (log) May 19 10:17:44 rtpproxy[2529]: DBUG:handle_command: received command "29304_278705 P-1 B2B.256.470174 /usr/local/src/rtpproxy/sounds/ring session d20fbd749deed7e1f54460af276dee6d-0ead;1 " May 19 10:17:44 rtpproxy[2529]: INFO:handle_play: -1 times playing prompt /usr/local/src/rtpproxy/sounds/ring codec 8 May 19 10:17:44 rtpproxy[2529]: DBUG:doreply: sending reply "29304_278705 0#012" Everything works fine, a long time ago i have modded the rtpproxy a bit so when he sends the audio, he sends it with 20ms ptime instead of default 10ms, and i have totally forgot where is that part, i am digging into sources and not able to find it. Dear list if somebody remembers where is this damn setting in sources, i would be glad to hear from you. Thank you
