Caller ID

Updated 2026-10-23 · By the SMS Conecta team (SMSConecta Inc.)

Short answer: Caller ID is the calling party's phone number — sometimes a name as well — shown on the recipient's phone before they pick up, letting them decide whether to answer or call back later. On SIP calls, that number rides along in headers like From and P-Asserted-Identity.

Whatever number your contacts see affects whether they answer at all, so showing a local number in their own country often helps.

How it works

The originating network passes the calling number along with the call setup. Displaying a name is a separate lookup (CNAM, in North America). Regulators like the FCC ban spoofing caller ID with intent to defraud or harm someone, and frameworks such as STIR/SHAKEN sign caller ID specifically to combat that spoofing.

Frequently asked questions

That depends on the recipient's carrier; CNAM isn't a feature SMS Conecta lists.

Why bother with a local caller ID?
