Subject: [Megaco] Question about ServiceChangeAddress

Hi,

   In the "Registration" example from "draft-ietf-megaco-callflows-00.txt", MG generates the registration message to the default port of MGC, it also specifies the service change address to which the MGC has to send further messages. MGC also specifies the new transport address so that when MG generates any messages it generates to this address instead of the default transport address for the MGC.
   It seems simple when UDP is used as the protocol transport. But in the TCP case, the existing connection shall be closed, and which side should initiate a new one? Still MG? But the first subsequent message may be sent by MGC. Or shall the address change only apply in UDP case?   

Best Regards,
