//should just offer a way to send a SIP message with the appropriate branch id for the dialog.
//should also offer a way to receive SIP messages and parse them into the appropriate dialog.

//on the implementation side, we should then be able to create a dialog and then register event handlers for the different SIP messages that we expect to receive.
