Chapter 3 Configuring the Cisco IPVC 3500 Series Gateway
Configuring Gateway Settings
Configuring the Gateway for Peer-to-Peer IP Connectivity
In the IP Connectivity section of the Settings tab, you can configure the gateway for peer-to-peer IP
connectivity.
Procedure
Step 1
In the Gateway interface, on the sidebar, click
Gateway
(if not already selected).
Step 2
Click the
Settings
tab.
Step 3
Click the
IP Connectivity
button.
Step 4
In the
IP connectivity mode
field, choose
Peer-to-Peer
.
Caution
Changing this setting causes the gateway to reset.
Step 5
In the
Peer hunting mode
field, choose one of the following options:
•
Always start from first peer
—The gateway attempts to connect a call to the first peer device on
the Peer list section. If the call fails due to one of the H.323 call disconnect reasons (see
About
Peer-to-Peer H.323 Call Disconnect Reasons, page 3-8
), the gateway tries each peer device in the
Peer list section in order until the call is successfully connected. If the gateway fails to connect the
call after trying all the peer devices on the list, it rejects the call.
•
Always start from last successful peer
—The gateway attempts to connect a call to the last peer
device in the Peer list section with which a call was successfully established. An arrow in the Peer
list section indicates with which of the peer devices a call was last connected successfully. If the call
fails due to one of the H.323 call disconnect reasons (see
About Peer-to-Peer H.323 Call Disconnect
Reasons, page 3-8
), the gateway tries each peer device in the Peer list section in order until the call
is successfully connected. The arrow moves to the peer device with which the call connection is
successful. If the gateway fails to connect the call after trying all the peer devices on the list, it
rejects the call and the arrow indicates with which peer device a call was last connected successfully.
This is the default setting.
•
Round Robin
—As the
Always start from last successful peer
setting, except that the arrow
advances to the next peer device in the Peer list section even if the call connection succeeds.
Note
The peer hunting process starts when any of the following events occur: the gateway fails to
establish a Transmission Control Protocol (TCP) connection to the specified peer device after a
timeout; the gateway receives a “Release Complete” message from a peer device with a “No
Resources” call rejection reason, or one of the other reasons that the Peer-to-Peer disconnect
reason add advanced command specifies; or the gateway establishes a TCP connection to the
specified peer device, but does not receive a valid H.323 message from the peer device after a
timeout.
Step 6
In the Peer list section, you can configure peer devices currently configured to work with the gateway.
The Peer list section displays all configured peer devices in a table with the following columns:
•
Peer #—The sequential number of the peer in the list.
•
Description—The description of the peer device.
•
IP Address—The peer IP address.
•
IP Port—The peer IP port number.
