remove the traffic_after_tick check because it caused problems with jingle. we need a tick every 25 seconds, but with that, the conncheck happens at 0s, and when the keepalive gets called @25s, it gets skipped and we only send our first keepalive after 50seconds... which means that jingle which stops processing if it doesn't receive a ping after 30 seconds, will stop playing our audio from 30 seconds to 50 seconds...
