SIP Disable Media Inactivity Timer for Calls Placed on Hold

Hardware-based media flow guard timers detect when a call has lost media while it is being relayed through the Oracle® Enterprise Session Border Controller. In response, the system tears down the call.

You can configure disable-guard-timer-sendonly to disable media inactivity timers for calls placed on hold. The Oracle® Enterprise Session Border Controller disableds initial and subsequent guard timers for media when the SIP or IWF call is put on hold with a 0.0.0.0 address in:

• The c=connection line
• An a=inactive attribute
• An a=sendonly attribute

It should be noted that disabling the media inactivity timers will also disable the guard timers for calls which are not necessarily on hold, but simply are one-way audio applications.
