My recommendation

• Start with Twilio if you want the easiest and most documented solution.
• Consider Telnyx or Vonage if you want more telecom control or potentially better pricing.
• Consider Plivo if cost matters and your routing needs are straightforward.

What “routing” usually means

Most APIs let you route calls by:

• time of day
• caller ID
• IVR menu (“Press 1 for sales”)
• agent availability
• geographic region
• queues / ring groups
• forwarding to SIP, phone numbers, or apps
