AI voice agents on a 917 New York number
Bring a 917 number you already own from Twilio, Plivo or Vonage, and connect it to an agent over SIP.

New York City, where every 917 number rings.
What a 917 number actually is
The 917 area code covers all five boroughs of New York City. It went into service in 1992, originally for mobile phones and pagers across the whole city rather than for one borough, which is why it overlaps every other New York code.
A call from a 917 number is most likely a mobile phone anywhere in New York City. Because 917 spans all five boroughs, it doesn't narrow down where the caller is.
