You do not have to tear down manually media sessions. The sessions are automatically managed (added/deleted) per call by MediaProxy server. Just make sure you rewrite the contact and forward the RE INVITES in ser.cfg. With a correct ser.cfg configuration you see in the status page that the call is on hold and becomes active once you return from hold. Adrian Hello, What is the default behaviour for mediaproxy on call holds? Is there a need to tear down an open media session when a re-Invite is received with the typical on-hold values? Or is this handled by the dispatcher automatically? Thanks, best regards, Martin
