RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator's Guide
Do not enable PSTN/ISDN access without defining the dial-in numbers range and/or the use of
"Dial-In Numbers as Prefix Range". If you enable the PSTN/ISDN access without the definition of the
dialing parameters, people can dial in to the gateway from outside the organization and then make
long distance calls at the 'host' expense.
The new Gateway Profile is added to the list.

System Configuration

For details about adding and modifying system flags, see

Displaying the Connection Information

You can hide the connection indications displayed on the participant's screen during the connection phase
by changing the system configuration and manually adding and setting the system flag

By default, this flag is set to NO and all connection indications are displayed.

Enabling PSTN dial-in using GK prefix

The feature is enabled when setting the flag USE_GK_PREFIX_FOR_PSTN_CALLS to Yes.
For more details, see PSTN Dial-in Using GK Prefix

Gateway Calls Redialing

The Gateway can redial to numbers that are wrong, or busy or there is no answer.

Gateway Redial Guidelines

● Redial with IVR is supported:
 In CP environments only.
 For H.323, SIP and ISDN calls.
 When using the Collaboration Server's Inviting Participants using DTMF functionality.
● Redial with IVR is not supported:
 When using PCM's Invite Participant functionality.
 Dialing multiple destination numbers.

Redial on Wrong Number

An IVR message is played requesting the user to enter a new number, followed by up to five redial attempts.
If all redial attempts fail, the user is alerted by an IVR message that the dialed number is unreachable,
followed by reorder tone and disconnection.
