T46G RTP Multicast - re-activate stream

[briankelly63]

When a multicast RTP stream begins the phone activates it speaker and the stream can be heard.
If you pick up the receiver and hang up the connection to the stream is ended.
I would like an option that re-activates the speaker whenever the phone is idle and the stream is present.
In other words I'd like to prevent the stream from being deactivated.

This feature would be important for emergency use!
