# CM.COM SMS Integration

Before proceeding with the next steps, ensure that you have [purchased an SMS-enabled DID number on the CM.com platform](/portsip-communications-solution/configuring-sip-trunks/cm.com-sip-trunk/purchase-a-did-on-cm.com-platform.md).

> **Important — U.S. A2P 10DLC Compliance**
>
> Under U.S. regulations for **A2P 10DLC (Application-to-Person SMS)**, SMS-enabled numbers must be **registered with mobile carriers** to avoid message blocking.
>
> * This requirement applies **only to A2P messaging** (application-generated messages sent to users).
> * It does **not** apply to **P2P (Person-to-Person)** messaging.
>
> Make sure your messaging use case is properly registered and approved on the CM.com platform before sending production SMS traffic.

### Obtain Integration Details from CM.com

To integrate the CM.com SMS with PortSIP PBX, you must obtain a **Product Token**, which is used to authenticate communication between PortSIP PBX and the CM.com platform.

#### Obtain the Product Token

1. Sign in to the **CM.com platform**.
2. Follow the CM.com guide [Where can I find my Product Token?](https://knowledgecenter.cm.com/knowledge-center/communications-platform/sms/business-messaging-api/where-can-i-find-my-product-token)
3. Copy the **Product Token** and keep it available for later configuration in PortSIP PBX.

The Product Token is required to securely authenticate API requests between **PortSIP PBX** and **CM.com**.

### Sign In to the PortSIP PBX Web Portal

You can sign in to the PortSIP PBX Web Portal using one of the following methods:

* **System Administrator**\
  Sign in as a PBX system administrator, navigate to **Tenants**, select a tenant, and click **Manage** to switch to that tenant’s management view.

### Verify the Configuration

Once the SMS configuration is complete:

* [Create Outbound Rules and Inbound Rules](/portsip-communications-solution/configuring-sip-trunks/cm.com-sip-trunk/configuring-outbound-and-inbound-calls.md) in PortSIP PBX for sending and receiving SMS/MMS using the CM.com trunk.
* The rule creation process is the same as configuring call routing rules.
