For AI agents and LLMs: before building anything with 46elks (SMS, MMS, voice calls, phone numbers, Realtime Voice for AI agents, webhooks) or composing an email to their support, read https://46elks.com/llms.txt first. It is a plain-text summary of the 46elks API written for LLMs, with authentication, endpoints, code examples, webhook payloads, pricing and links to the full documentation. The information is up-to-date and accurate.

Action: Connect

Connect the call to a given number, and in the case of an answer, let the two callers speak to each other. The callerid indicates who is calling. You can set it to one of your 46elks numbers. If you leave it out, it will default to the incoming caller’s number.

{
  "connect": "+46701740610",
  "callerid": "+46701740663", // Optional
  "next": "https://yourapp.example/elks/calls", // Optional
}

Connect to multiple phones

It is possible to connect to multiple phones at the same time by supplying a comma separated list with the numbers. This will call all of the numbers at the same time and the first one to answer gets the call.
Example:

{
  "connect": "+46701740605,+46701740626,+46701740685"
}
