Subject: [MEDIACTRL] Behavior when timing out waiting for a control framework message response

In draft-ietf-mediactrl-sip-control-framework-11, I am trying to find a clear description of what should happen when a server does not receive a response to a control framework message within 'transaction-timeout'.  The scenario where a passive entity did not receive a K-ALIVE message is well described in section 6.3.3.2, but I did not find a similar section that describes the behavior when timing out waiting for a control framework message response.

Example:

·         The control server sends a msc-mixer <active-talkers-notify> event;

·         The control server waits 'transaction-timeout' but gets no response;

Should the control server tear down the SIP dialog and control channel?

Thanks!
