Static and Dynamic IP addresses
DHCP (Dynamic Host Configuration Protocol)
DHCP is used to assign IP addresses to each device on a network from a central
server. A DHCP assigned address can change if the server or eyesite 550 is reset or
rebooted, meaning that your IP address may change if you use DHCP.
To ensure constant availability of your eysite 550, you must either register it with a
gatekeeper (see H.323 settings), or fix the IP address by changing the setting from
DHCP to static once configured.
UDP Port
The UDP port number can be configured for two purposes.
1. To allow incoming calls to be forwarded to the eyesite 550 using the firewall’s
external IP address, and a port forwarding function in the firewall
2. To create a video/audio port stream range that matches the range of ports
opened in the firewall for other H.323 devices (typically 5000 to 5010).
To setup the unique UDP Port number on the remote video system
Max Data Speed Select the Max Data Speed using the Right or Left arrow
keys on your key pad. The Max Data Speed feature is for
limiting the bandwidth used for incoming calls. This allows
you to force all incoming calls to connect at a lower speed in
situations where bandwidth is limited. Options include 32K,
48K, 64K, 96K, 128K, 160K, 192K, 256K, 320K, 384K.
Auto Answer The Auto Answer feature is for setting the number of rings to
automatically answer the call. The default is 4 rings.
Use the Right or Left arrow keys to set Auto Answer between
1 RING and 8 RINGS or OFF. If OFF is selected calls are
not answered automatically.
