I'm having problem with my VoIP application. My app uses Callkit and VoIP push notification to make SIP calls between same app. Sometimes after taking the phone the call doesn't start. I found out iOS is not sending back audioSession didActive response to my app. Is this known issue or bug?

Yes, this is a known bug. There's an extended thread around it here, along with my suggested workaround, which is to call "setConfiguration" before you report any call.
