| Description | This object enables the user to provision the
way signaled events from CA are handled
by the gateway. This is configurable on
a per MGC redundancy group, per protocol basis.
If the protocol is MGCP 1.0 the default of this
object is 'deleteOnlyNegatedEvent', else it is set
to 'deleteEventNotPresent'.
If this object is set to 'deleteOnlyNegatedEvent',
then the signal currently active on a
endpoint/connection can be turned OFF only by
parameterizing it with a (-)
for eg: S: T/co1(-)
will turn off co1 event on an endpoint.
And can be turned ON by just
providing the signal name or by parameterizing
the signal name with a (+)
for eg: S:T/co1(+), L/hd
will turn on co1 and hd events on the endpoint.
If this object is set to 'deleteEventNotPresent',
then the signal/s can be turned OFF by
providing empty S: list.
The signal can be turned ON by simply
providing the signal name.
for eg: S:
will turn OFF all active signals on the endpoint
S: T/co1
will turn ON co1 signal.
The configuration of this object only applies to
on/off signals and not for brief or timeout signals.
MGCP 0.1 specification says if an empty signaled
list is provided it is meant to turn off all the
currently turned on signaled events. However
in MGCP 1.0 specification, it says that unless
specifically requested by the CA to turn off
(signal is parameterized by a (-)) the signal
cannot be turned off, in other words an
empty signal list does imply that the currently
active signals should be turned off.
Although the behavior of the gateway is
specified in the specs, some MGC
may not follow the MGCP 1.0 spec. Hence
this MIB serves as an interop knob.
This object has no relevance when the protocol
is SRCP. |
