This is still serial forking. Imagine the following scenario: You are
calling a phone number, you dial first provider who starts playing a dial
tone then uses an UPDATE to connect you to a media server to play an
announcement after which your call goes to voice mail (another dialog and
another SDP). This is all fairly legal and not unusual for SIP scenarios.
Nothing to do with party lines.
