# Calls Routing Incorrectly After Updating Your Invoca Tag to Use Both Forward to Detected Destination and Forward to Marketing Data Field

> Misrouted calls right after a Tag update are usually stale visitor sessions — they should resolve once the attribution window expires.

## Symptoms

Calls are misrouted even after updating the Invoca Tag.

**Applies to:** Invoca call routing

## Cause

If a visitor was on your webpage before the Tag update, their session is still tied to the old session information, which leads to unintended routing.

## Resolution

This should resolve itself once the attribution window expires for visitors who were on your site before the update.

If misrouted calls remain consistent week over week rather than tapering off, there's a different underlying issue. Reach out to your account team or [support@invoca.com](mailto:support@invoca.com) for further troubleshooting.
