Step 1: There must be a call between two extensions. Use ListActiveCalls command to find the call ID of the call you want to hold. You can find the CallId in the response, between one of the <CallId></CallId> nodes.
Step 2: Initiate a hold using a HTTP request as seen in the picture above. Paste the call ID you found in Step 1 in the CallId parameter of the request.
