Calls are not getting in on first or second attempt

WARNING[32633] netsock2.c: Unable to set SIP RTP DSCP TOS value to 184 (may be you have no root privileges): Operation not permitted

This warning appears in the asterisk logfiles when someone calls. Ive mistakely type “amportal chown” on my terminal of PBX server that was running asterisk 1.8 . After that, this error shows in the logs and sometimes the caller doesnt succeed on getting the call on his first try. Can someone help me? Thankyou very much!
