•
Calls—Displays “Yes” or “No” to indicate whether or not there are currently any active calls
between the peer and gateway.
To change the order of peer devices used in peer hunting, select a peer device and click the up or down
arrow button to change its order.
To add or edit a peer device, click Add or select the peer device and click Edit . Perform the following
steps in the Add peer or Edit peer dialog box:
a.
In the IP Address field, enter or edit the peer IP address.
Note
Two peers cannot have the same IP address or host name/Uniform Resource Locator (URL).
b. In the IP Port field, enter or edit the peer IP port number.
c.
In the Description field, enter or edit the description of the peer.
d.
Click Upload .
Note
You cannot add a single peer to the Peer list section more than once.
To delete a peer device, select the peer device and click Delete . Deleting a peer does not cause its active
calls to disconnect, but no new calls route to the deleted peer.
Note
The peer hunting process stops when one of the peer devices accepts the call or when the call is
rejected with a disconnect reason. When a gateway has scanned the Peer list section and still
cannot connect a call then the following rules apply: if at least one of the peers rejected the call
due to capacity overload, the call rejection reason (towards the call originator) is “No
Resources”; in all other cases, the call rejection reason is “Unreachable Destination.”
Step 7
In the Peer hunting timeout (sec) field, enter the length of time (between 1 and 10 seconds) for which
the gateway waits for a Transmission Control Protocol (TCP) response from each peer device contacted.
The default value is 5 seconds.
Step 8
Select the Accept calls from defined peers only check box if you want the gateway to reject incoming
calls from IP-side entities not defined in the peer list. If unselected, the gateway allows incoming calls
from IP-side entities not defined in the Peer list section.
Step 9
In the Reject calls from peer devices when less than n B channels are free field, enter the lower
capacity threshold for rejecting calls from H.323 peer devices. The default setting is 6.
