First steps

Enabling port reservation prevents:

 the Create new conference option being displayed, even on auto attendants that are set up to have this

option and therefore ad hoc conferences cannot be created when port reservation is enabled

 you creating a new auto attendant with this option

 users calling in to the MCU with an unknown E.164 number setting up a new conference, even if

Create new conference has been set in the Conference settings page. See the online help topic

“Configuring global conference settings”. In this case, the user is disconnected

Port reservation is enabled on

Settings > Conferences. See the online help topic “Port reservation” which

explains the advantages and consequences of enabling port reservation.

Configuring auto attendants (MCU and IP VCR)

When an endpoint connects to the MCU or IP VCR, the default auto attendant may be displayed with a

menu of options and an audio prompt is heard (see the online help topic “Using an auto attendant”).

Whether the auto attendant is displayed depends on how the units are set up.

Auto attendants on the MCU

The Codian MCU can have many auto attendants (otherwise known as Interactive Voice Responses or IVRs)

and menu structures can be setup by configuring multiple linked auto attendants. See the online help topic

“Adding and updating an auto attendant”.

We recommend that you do not change the setting while there are active conferences. If you

enable port reservation, all ad hoc conferences are destroyed and their participants are

disconnected. Also some participants of scheduled conferences may also be disconnected — if

the number of ports reserved for a conference is less than the number of active participants at

the time you change mode. See the online help topic “Reservation of MCU media ports”.

VNC connections are video-only and therefore will never be allocated an audio-only port.

Streaming requires one video port per conference but any number of viewers can steam the

same conference on that port.

When a participant connects to an auto attendant, a port is borrowed from the pool because

the MCU does not know which conference to allocate the connection to until a conference is

selected. This means that if that participant is using the last media port and another endpoint

connects directly to a conference, the auto attendant link will be dropped.

Even when port reservation is disabled, you can set a maximum for the number of video and

audio-only participants in a conference. See the online help topic “Adding and updating

conferences”.
