UNIQUE KEY `presentity_idx` (`username`,`domain`,`event`,`etag`), ``` This approach breaks the uniqueness of etag, which is intended to differentiate records , especially in cases such as parallel calls, or when using kamailio as a forking proxy. Instead of overwriting the etag with the static offline marker, this patch appends the marker to the existing etag value. This ensures the offline flag is retained while preserving the uniqueness of the etag. The deletion query was also updated accordingly: it now identifies offline records using a LIKE '%*#-OFFLINE-#*' clause. Based on testing, the duplicate key errors no longer occur, and the cleanup logic now behaves as expected. This patch improves the reliability of presentity cleanup without requiring schema or index changes. Please consider merging into master. Thanks!
