3. If a trunk is only for outgoing calls, don't specify a context.
Then it will default to 'default' (or whatever you configured in the
global sip settings) and you are not accepting calls there either right
? (maybe some for ENUM stuff, but those should be named anywayz)

Not using a trunk for outbound calls is as simple as never using
Dial(SIP/trunkname)


I think 3. is all we need and already available at the moment.
