This should be done before a release:
* ReleaseCallPartyConnection
* Announcements
	Should there be an internal or an external SRF?
* Terminating triggers
* Trigger management
	Web interface?
	SOAP interface?
	Distributed Erlang interface?
	CORBA interface?
* Triggers should contain service id

This would be very nice to have:
* Reuse connection to phone for SMS
* Implement SMS reception for (simulated) phones

This would be nice to have for some people:
* Support for message driver protocol
	Should there be more TCAP handling?
* Support for CAPv2
	Could impact be reduced to encoding decoding?
	If not, at least simple_call and port_handler etc. can be reused

This is not necessary, but may be done if time permits:
* SSF-SSF communication
	How will routing be handled?
