AI voice agents on a 332 New York number
Bring a 332 number you already own from Twilio, Plivo or Vonage, and connect it to an agent over SIP.

Manhattan, where every 332 number rings.
What a 332 number actually is
The 332 area code serves Manhattan in New York City. It went into service in 2017 as the newest overlay on 212 and 646, so all three cover the same ground. 332 exists because Manhattan ran out of both 212 and 646 numbers.
A call from a 332 number is most likely a recently issued mobile or business line in Manhattan. Four codes now serve the same area: 212, 646, 332 and 917.
