Hi, I'm using latest kamailio 5.6.2 and rtpengine. I need to play announcement to both parties when call is answered by callee. Now I run play_media in event route but when audio start announcement sounds like we have a 50% packet loss. After it is completed there is no problem with audio both sides. I figured out that if i do block_media() my announcement play perfectly but i dont understand how to do unblock_audio() after announcement ends. Appriciate any help! here is my code: event_route[dialog:start]{ xlog("L_INFO", "dialog started, received 200OK"); block_media(); play_media("all file=/usr/local/src/myfile.mp3"); #unblock_media(); } -- Best Regards Stepan Kislovich
