# PreSense: Real-Time Data Transfer

> PreSense delivers the data Invoca already collects from a caller's web session — like the ad they clicked or items in their cart — to your call center agent before they pick up the phone.

PreSense delivers the data Invoca already collects from a caller's web session — like the ad they clicked or items in their cart — to your call center agent before they pick up the phone.

With this information, agents can better anticipate caller intent, conduct better conversations, and close more conversions.

## The three parts of PreSense

* **Pre-transfer Invoca webhooks** — deliver data from a caller's web session before your agent picks up
* **Invoca SIP Integration** — sends Invoca data as headers alongside phone calls
* **A Call Center as a Service (CCaS) integration** — connects Invoca to your CCaS tool, such as Five9

Your organization may use all three, or mix and match depending on your technology setup. Talk with your Invoca Account Manager or Customer Success Manager to discuss the best PreSense configuration for your account.

## Common use cases

**Sending shopping cart and ad-click data to a SIP-enabled phone display:**

1. Capture your caller's browser data using custom Marketing Data fields.
2. Set up your Invoca SIP Integration to pass that data as SIP headers.

**Routing high-intent calls directly to your best-performing agents (via a CCaS tool):**

1. Create a Signal based on characteristics of high-value callers, such as their landing page, browser data, or Signal AI insights.
2. Work with your Invoca Customer Success Manager to set up a CCaS integration using a pre-call webhook, routing to the best agent as determined by your CCaS.
3. Include that pre-call webhook in your Invoca campaign's call treatment routing tree.
