### Adding a Cal.com Step in a Callers Campaign

**Email Handling for Cal.com Integration:**
Callers will attempt to obtain the contact's email in the following order:
1. From the contact field (if available)
2. From the SIP headers (if provided by your telephony provider)
3. By extracting it from the conversation transcript
If the email cannot be found, the meeting will be scheduled without sending an invite to the contact.

* Choose the relevant **event** from the dropdown.
