Move Audio from any Endpoint to Another Seamlessly
When a call has been answered on a single endpoint, such as the mobile client, the ability to move this call seamlessly to another endpoint is difficult. There's call park, but that doesn't work with a mobile client and doesn't exist online as of this feedback. You can occasionally transfer to yourself, but this may not work if the call was sim-ringed to another device. Both of those options can be clumsy and involve a bit of apologizing to the party on the other end of the line as they may hear hold music. There are situations where the call is just stuck where you answered it. I would like to see this improved, at the least for transferring audio between the mobile client and other devices.
