Chapter 19-Gateway Calls
Polycom, Inc. 19-23
• Rejected - the far endpoint has rejected the call. In such a case, the system will try to
connect using another communication protocol.
• Unreached - the number could not be resolved by the gatekeeper or the SIP proxy or
could not be found on the network. In such a case, the system will try to connect using
another communication protocol.
• Failed - any reason causing the system not to complete the connection process. In such a
case, the system will try to connect using another communication protocol.
You can hide the connection indications by changing the system configuration. For more
details, see "System Configuration” on page 19-21.
Gateway Session Parameters
Gateway Session Name
The Collaboration Server creates a new conference that acts as a Gateway Session with a
unique ID whose display name is composed of the following components:
•The prefix GW_,
•The Gateway Profile display name. For example, Default_GW_Session
• (number) where the number is a gateway conference counter.
For example: if the Gateway Profile display name is Default_GW_Session, the conference
name will be GW_Default_GW_Session(001).
Conference ID:
The ID of the new conference is assigned randomly by the MCU.
The Gateway Session automatically ends when only one participant is left in the session.
Connected Participant Parameters
Once this conference is created, the calling participant is connected to it and one or several
dial-out participant(s) are automatically created and added to this gateway session. The dial-
in participant is also identified as the chairperson of the conference.
The connecting (dial-in) participant name is taken from the endpoint. If the endpoint does
not send its name, it is derived from the Gateway Profile display name and it includes the
Gateway Session name, underscore and a random number is displayed (between brackets),
for example, GW_Default_GW_Session(001)_(000).
The name of the destination (dial-out) participant is taken from the endpoint. If the endpoint
does not send its name, it is taken from the dialed number. If the dialed number was an IP
address, the system displays underscores instead of dots, for example, 172_22_172_89.
Participants connected to a gateway session are monitored in the same way as participants
connected to ongoing conferences. For details, see RealPresence Collaboration Server 800s
Administrator’s Guide, "Participant Level Monitoring” on page 13-23.
Direct Dialing from ISDN/PSTN Endpoint to IP Endpoint
via a Meeting Room
Dialing from an ISDN endpoint to a specific IP endpoint using the Gateway Profile is a two-
step process (dialing to the Gateway and then entering the number of the destination IP
endpoint).
