These are most likely Out of Session calls — calls to a RingPool number that weren’t served to a website visitor by the Invoca tag, so no marketing data was collected.
What causes this
If a RingPool number is called directly without being served by the Invoca tag, the call still connects — but because it isn’t part of an active session, the Invoca tag never collected marketing data to apply to it. The values for those fields are blank. Out of Session calls can happen when:- A repeat caller dials an old RingPool number saved in their phone.
- The call is spam.
- A RingPool number was hard-coded on a website outside of the tag’s normal serving process.
