hideInGuideShowcase: true Caller ID vs. Caller Name - The Caller Name (**CNAM**) is a feature that displays your Name or Company Name on the Caller ID display of the party you are calling. When it is set up, your Caller ID Name will display as text along with your Caller ID Number. The Caller ID is the actual phone number calling in, whereas the accompanying text that provides the identifying name for that number is called CNAM (a.k.a. “Caller Name”). When a phone call is made, the Caller ID (CLID) is routed to the destination’s carrier for delivery. The Caller Name (CNAM) text data is not sent out by the originating carrier, as they are separate services. When the call arrives, the carrier for the destination end of the call will reference the inbound number against its local CNAM database. At this point, both a CLID number and CNAM text are usually delivered to the recipient’s (called party’s) phone when it rings through. How to Set CNAM for PSTN to PSTN calling - :::info CNAM Industry Limitations CNAM is disallowed on toll-free numbers, the actual number is the only display option when creating calls. CNAM only works on PSTN calling, not SIP to SIP calls. See Caller ID below to learn how to set a caller ID for SIP calls.

Set the **Caller ID** field within [SIP Endpoint settings](/voice/getting-started/sip/set-up-a-signalwire-phone-number-with-a-sip-endpoint) to display caller ID on SIP to SIP calls. If you choose to set the **Send As** field, that will display one of your purchased or verified numbers, but it will only show for calls to PSTN numbers. **Caller ID** is the only way to display the caller ID for SIP to SIP calls. .default})
