I don’t recall seeing the rtp and jitter entries being logged regularly at other customer sites, so I am probably missing something obvious. This site is running asterisk 18.17.1. I enabled debugging to try to help track down an issue. The problem is the debug_log file is filling rapidly with entries like the following.

I tried the following to disable these entries, but none of them stopped the entries in the log core set debug category off rtp core set debug category off rtcp rtcp set debug off rtp set debug off
