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.
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
Sign in to the CM.com platform.
Follow the CM.com guide Where can I find my Product Token?
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.
Configure SMS with a CM.com Trunk in PortSIP PBX
Before configuring SMS in PortSIP PBX, ensure that you have already configured a CM.com SIP trunk using one of the following guides:
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.
Tenant Administrator Sign in directly as a tenant administrator to manage your own tenant.
For more information, refer to Tenant Management.
Add an SMS Configuration
Follow the steps below to configure SMS using the CM.com trunk:
Sign in to the PortSIP PBX Web Portal.
From the left-hand menu, navigate to SMS/MMS.
Click Add.
Configure the following settings:
Trunk Select your previously configured CM.com Trunk.
Sender ID
If you have configured a Sender ID in the CM.com platform, enter it here.
If left empty, PortSIP PBX will use the DID number associated with the CM.com trunk as the Sender ID.
Product Token Enter the Product Token obtained in the Obtaining the Product Token step.
Click OK to save the configuration.
After saving, you will be redirected to the SMS/MMS list page.
Copy the Webhook URL
To complete the integration:
Select the SMS configuration you just created and click Copy Webhook, or
Double-click the SMS configuration and manually copy the Webhook URL.
This Webhook URL is required for receiving inbound SMS/MMS messages from the CM.com platform.
Configure the Webhook in the CM.com Portal
Log in to the CM.com Portal, navigate to the SMS channel settings.
Configure the Webhook URL by pasting the Webhook copied from PortSIP PBX.
Set the HTTP method to POST.
Save the configuration.
Verify the Configuration
Once the SMS configuration is complete:
Create Outbound Rules and Inbound Rules 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.
