Using Device tabs to configure the security gateway
Issue 4 May 2005 75
The IP address. This IP address must be within the same subnet as the DHCP server.
Avaya recommends that you use an IP address for the device that falls into the DHCP
subnet, but not in the DHCP range.
4. Click Add, and then click OK.
To add an IP telephony device to the security gateway:
1. Click IP Telephony. The IP Telephony Settings dialog is displayed.
2. Enter the following information
TFTP File Path Name. The TFTP file path name is used when the TFTP file path is other
than the default path.
Definity CLAN Port. The port number for the Definity server. The default port is 1719. The
port range is 1 to 65535.
Option 66. The standard DHCP option for TFTP server.
IP Telephony Domain. This is the domain name that the IP telephone device is assigned.
!Important:
Important: When symbolic host names are included in the TFTP server or CLAN lists, the IP
telephone will append the IP Telephony Domain name (if entered) to t he list entr y
in order to create a fully qualified domain name (FQDN). Y ou can, howev er, enter
host names using the FQDN form of <myhost>@<mydomain>.<toplevel
domain>, in which case you should leave the IP Telephone Domain name field
empty.
Also, be aware that the current version of IP telephone firmware will truncate the TFTP
and CLAN lists to a maximum of 255 characters each. Thus, when using the FQDN
form of host name entries, it would be possible to exceed that limitation very quickly.
TFTP Server. This is the server on which the latest version of the IP telephone firmware
is maintained for upgrade purposes. A maximum of five TFTP servers with IP addresses
or symbolic host names can be configured on security gateways running VPNos 4.6 and
higher.
Definity CLAN List. The IP address of the Definity Clan server. A maximum of 20 CLAN
IP addresses or symbolic host names can be configured on security gateways running
VPNos 4.6 and higher.
3. Click OK, and then click Save.
Note:
Note: When you configure an IP telephone, secure tunnels are created for TFTP and
Definity Clan. However, if only VPN users are connected, the secure tunnels are
created on demand. That is, the secure tunnels are created only when traffic
exists on the associated tunnel.
