Placing a call via API always creates a conference call

[Bekir_Khan]

Hello,
I am creating a call via the following API : POST /api/v2/conversations/calls using the following request format :

{
   "participants": [
      {
         "address": "XXXXXXXXXX"
      }
   ]
}

This results in a successful call but it is a conference call which I do not need because my main aim is to merge two call conversations using the PATCH /api/v2/conversations/calls/{conversationId} API.

I have also tried calling the address using the following request :

{
 "phoneNumber":"XXXXXXXXXX"
}

The above creates a voice call but gets stuck in the "Contacting" Phase and never dails plus in this scenario I also do not see any external participants as I do with the conference call in the first request.

Are you merging active conversations? Referring to the relevant article on the Genesys Cloud Resource Center, merging two active conversations will create a conference call, by definition.

I actually enabled "Placing calls with another app?" via the Phone Settings.

Then because of that I could send single calls via the agent.
