transfer a P2P (VoIP) audio call towards an external number

Hi, when making a P2P audio call between 2 rainbow users from the same company, there's no option to transfer that call towards an external number..

when you make a "telephone call" (so no P2P VoIP) you do get the option to transfer the call.. but this is confusing for the end users.. they need to decide what type al call they need to start  (telephony call or P2P VoIP) that will give them the best experience 

this option is available in Teams..
