Ignore SDP
Version
By default, the gateway will honor the session version
number in SDP packets and will only modify the SDP session
if the version number changes.
Switch this option off to force the gateway to ignore the SDP
session version number and treat all SDP data as new data.
This is required for devices that send non-standard SDP
packets (observed with Microsoft OCS).
By default this option is on.
Direct media
The value of parameter direct media is one of them (no, yes,
nonat, update, outgoing).
Default value is yes.

Choosing 'no' will disable all transfers (unless enabled in
