Remote Site Parameters; Remote Phone Mac Address - ESI E-Class Installation Manual

Programming information

Remote site parameters

• IP address — The address the Remote Phone will use. This can be either a public or private
address. [Item 4 in Figure 1, below.] The Remote Phone can only use a static address. If a static
public address is not available a NAT router must be used. In that case, the Remote Phone IP
address will be a private address on the remote site network. (Note that the Remote Phone IP
address cannot be the same as the PC address [Item 5 in Figure 1, below].)
• Remote Phone gateway IP — If the Remote Phone uses a private IP address, this will be the
internal network address of the remote site gateway. [Item 6 in Figure 1, below.] If the Remote Phone
use a public IP address, this will be the ISP gateway's IP address. This is commonly referred to as
the default gateway.
• UDP Port number — The port number that the remote phone will use for access through the
gateway at the Remote site.

Remote Phone MAC address

The Remote Phone MAC address is unique to each Remote Phone, and is preprogrammed. You'll need
this address for programming the IP PBX.
To determine the MAC address for a Remote Phone, power up the phone and wait; soon, the Remote
Phone's display will show the MAC address (for approximately 30 seconds).
