> We now have:
> * Two party calls, initiated both inbound and outbound
> * Endpoint location
> * Authentication
> * Reasonable media handling
> We should now be in a position to implement directmedia. This means we have to have support for re-INVITEs, as well as switching between a native or local bridge to a remote bridge.
> Direct media entails:
> * The basic setting which allows endpoints to re-negotiate their media upon call set up. This includes:
> ** Always attempt direct media
> ** Never attempt direct media
> ** Attempt direct media but only if we know the endpoints are not behind a NAT
> ** Attempt direct media, but use UPDATE only (this feels optional)
> ** Only attempt direct media on outgoing call legs (glare reduction)
> * ACLs that can be applied which prevent directmedia from being used if an endpoint registers from an IP that cannot re-negotiate the media successfully
