I have talked to technical support, this configuration option is not available which sounds RIDICULOUS! We need to post more here to escalate it up the wish list.
For the Record: I do not technically believe this is a feature to be escalated but a component that supports a feature already developed. I hope the development team will take that into consideration and please enhance the already existing feature of “Call”.
It is so frustrating to have to select an audio mic and headset every time I make a call, it should be able to set a default and always use this. Every video software and VoIP provider does this, why doesn’t HubSpot??
