Issue with Siri activation is iOS14

Hello,

We are using HFP profile version 1.6 . Our device is hands free device and it does not have a speaker. So we don't want to set up an audio connection with a remote device. Whenever an audio request comes we release the audio. 
 We want to connect remote AG device and activate voice recognition system (SIRI) over HFP using stack API "HFRESetRemoteVoiceRecognition_Activation()". So we have called this API to activate voice recognition (SIRI) over iphone and it gets activated successfully on IOS version 7 to 13. 

 But the recently released IOS version 14 shows different behaviour. When we call the API to activate SIRI , the SIRI gets activated after 20 seconds from call to API. I observed the debug logs for both IOS 12 and IOS 14. PFA logs. The initial procedure is the same in both the logs as in the below image.
But confirmation for voice recognition comes late for IOS 14. Also after confirmation IOS 14 sends call active indications though no call is active on the phone. There are multiple features added into IOS 14 SIRi. Also we have doubt that IOS 14 uses the latest version of HFP 1.8. So our concern is how to solve this problem with IOS 14.
