Purchase a DID on CM.com Platform

Before you can place or receive calls, you must have at least one active DID (or multiple DID numbers) on your CM.com account.

Note If you already have active DID numbers on your CM.com account, you can skip this section and proceed directly to trunk configuration.

Visit the CM.com website and sign up for an account.
After logging in, ensure that voice services (SIP trunking) are enabled for your account.

In the CM.com portal, follow the guide How do I order a new DDI number? to purchase the DID numbers.

After the DID numbers are successfully purchased and activated, you can proceed with configuring the CM.com SIP trunk in PortSIP PBX.

This step configures PortSIP PBX to use CM.com for outbound and inbound calling.
