Can't find call log from adb shell

Phone is a Samsung Galaxy E5 SM-E500m (lte, dual chip, codename e5lte). Android version 5.1.1 "lollipop" Stock ROM. I pulled the database file from /data/data/com.android.providers.contacts/databases/contacts2.db and tried to inspect it with both the DB Browser for SQLite and also the sqlite3 command-line tool. The file is 1.7MiB in size. It has 42 tables. From my research efforts, I was hoping to be able to see the call log in the calls table; but it is empty (0 records). Other tables in this db file all appear to have data. I also checked the file over /data/data/com.android.providers.telephony/databases/telephony.db but it does not appear to contain call logs (only 4 tables: android_metadata, carriers, siminfo and sqlite_sequence). Where else can I potentially find the call logs for this device? The call log is shown correctly in the Phone app. Thank you.
