Start time
The date and time at which the call was placed.
Source
The alias of the device that placed the call.
Destination
The alias to which the call was placed.
This may be different from the alias that was
actually dialed from the device, as it may have
been transformed either locally or before the
neighbor was queried.
Bandwidth Allocated
The amount of bandwidth allocated to this call.
Protocol
Shows whether the call used H.323, SIP, or
both protocols.
Route
The subzone or zone from which the call was
received and the subzone or zone to which the
call was placed.
Intermediary subzones are not shown
here. To see the complete route within
the VCS that the call took, click on View

Call disconnection works differently for
H.323 and SIP calls due to differences
in the way the protocols work.
For H.323 calls, and interworked H.323 to SIP
calls, the Disconnect command will actually
disconnect the call.
For SIP to SIP calls, the Disconnect command
will cause the VCS to release all resources
used for the call and the call will appear on
the system as disconnected. However, SIP
calls are peer-to-peer and as a SIP proxy the
VCS has no authority over the endpoints.
Although releasing the resources may have
the side-effect of disconnecting the SIP call, it
is also possible that the call signaling, media
or both may stay up (depending on the type
of call being made). The call will not actually
disconnect until the SIP endpoints involved
have also cleared their resources.
