 ## Requirements and Best Practices for Voice Communications
 
 1. **Monitor Call Patterns:** Regularly monitor call patterns to identify any unusual activity that may trigger spam filters. Avoid making a high volume of calls in a short period.
-2. **Use Caller ID:** Ensure that the customer’s caller ID is correctly set up and displays accurate information. This helps recipients recognize the caller and reduces the likelihood of being reported as spam (You can leverage the Azure Communication process for CNAM setup detailed [here](../telephony/how-to-manage-your-calling-identity.md)).

 3. **Obtain Consent:** Always obtain consent from recipients before making calls. This can be done through opt-in mechanisms where customers explicitly agree to receive calls from the customer’s business.
-4. **Provide Opt-Out Options:** Offer recipients an easy way to opt-out of receiving calls. This can be done through automated systems or customer service representatives.
-5. **Maintain a Clean Contact List:** Regularly update and clean customer’s contact list to remove inactive or incorrect numbers. This reduces the chances of calling numbers that may report customer’s calls as spam. Customers can leverage the Azure Communication Services Number Lookup API to help customers with that (more details [here](../../quickstarts/telephony/number-lookup.md)).

 ## Register in FCR
 
 The [Free Caller Registry](https://www.freecallerregistry.com/fcr/) (FCR) serves as a system for organizations that conduct outbound calls to secure approval for their phone numbers, ensuring they are not incorrectly tagged as “Spam Likely” or “Scam” by mobile service providers. This initiative is backed by leading US vendors (TNS, FirstOrion and Hiya) who develop mechanisms to label incoming calls with a “Spam Likely” indicator. The registry holds significant importance for entities dependent on outbound calls for their business activities, as it helps to prevent their calls from being intercepted or wrongly marked as spam by carriers or external services. We recommend that customers initiate the process of phone number registration to mitigate this risk.
