We are trying to initiate the call using https://github.com/ringcentral/ringcentral-softphone-js and stream some audio into the call after the call is answered. But it looks like `answered` events come too early before even the phone itself rings. Actually, it comes right after the call was created.
I am using the demo for outbound calls from the repository https://github.com/ringcentral/ringcentral-softphone-ts/blob/main/demos/outbound-call.ts
You can see in the logs that `ANSWERED` event comes in the same second as the previous event, right after the call was started.
It is a known issue if the callee is a RingCentral number, it will be answered immediately. It is by design. I don't like the behavior but I cannot change it. It's not due to the softphone SDK, it is a RingCentral server side behavior.
If you make a call to your own number (not RingCentral number). Make sure the callee is not a RingCentral number, and in theory, this issue will not be reproduced. I just tried my own mobile phone and it works as expected.
You can see that "SIP/2.0 183 Session Progress" at 10:46:47 and "SIP/2.0 200 OK" at 10:47:02. The 5 seconds difference is how long it took me to answer the phone call.

But we need this to create a call inside the company and stream the audio here.
Is there any other way to receive an event, maybe some custom event, when the call is answered?
Thanks.
I cannot help you on that. As I said, it is a server side behavior, not a SDK/client behavior. When you call a RC number, RC server will auto answer the call and play hold music to you.
So it's impossible to create a call and stream the audio after the real user answers the call?
Any chance to add a different event for that?
We really need this to create a "warm transfer".
I guess that you test by calling another user extension under the same account, right? If that is the case, can you test be making an outbound call to your mobile phone number (hope that you are in the U.S so you can make such local call.)
Yes, I was calling by extension under the same company account.
I tested the same code with a mobile phone number it works in the same way - the answered event comes immediately after the call was created.
