UDP ports to allow remote extensions and VoIP service providers to function
correctly. Please see the section Networking, Quality of Service, and Firewalls for
more information about port forwarding.
Local IP: the IP address for your Evolution Server on your Local Area Network.
Local Network: displays and sets the local network address and subnet mask of
the Local Area Network that your Evolution server resides on. If Evolution is
behind a NAT router this setting is used to determine which IP addresses are local
and thus be allowed access to Evolution configurations. If you have several local
networks that require access to Evolution set the Self Discovery option to Disabled
and list all your local networks separated by a comma (for example, for the two
subnets 192.168.0.0 and 192.168.1.0 enter the following:
192.168.0.0/255.255.255.0,192.168.1.0/255.255.255.0).
Gateway: the IP address of the default gateway for the Local Area Network.
Network Mask: the subnet mask for the Local Area Network.
Primary DNS: the IP address of the primary Domain Name Server to resolve
Hostnames to IP addresses.
Secondary DNS: the IP address of the secondary Domain Name Server to
resolve Hostnames to IP addresses.
Self Discovery: set to Enabled to allow Evolution to ping the Internet and learn
its external IP address and allow Evolution to calculate your Local Network.
Otherwise the external IP address must be manually configured. The external IP
address is used for remote extensions (remote extensions are telephones that are
connected through the Internet).
DHCP Server
DHCP Server: enables or disables the DHCP server feature built into Evolution.
The built in DHCP Server assigns IP addresses to your network devices including
VoIP telephones.
Note: Only one DHCP server is permitted on a Local Area Network. If the
Evolution DHCP server is enabled then other DHCP Servers on your network will
need to be disabled.
Starting IP: the lowest IP address that will be assigned to devices when DHCP
server is enabled.
Ending IP: the highest IP address that will be assigned to devices when DHCP
server is enabled.
Domain: the domain name that will be assigned to network devices when DHCP
server is enabled.
Discovery Mode: Configures Evolution and the DHCP
server for a specific discovery type. The Auto settings
(Auto-Polycom and Auto-Non-Polycom) discover new
telephones that are plugged in to your network and
automatically provision the telephones as an extension.
The Disc settings (Disc-Polycom and Disc-Non-Polycom)
discover new telephones that are plugged in to your
network and inform the administrator in the web interface
under Resources, Phone Extensions but the telephones are not automatically
provisioned. The Polycom settings (Auto-Polycom and Disc-Polycom) are
compatible with only Polycom telephones. The Non-Polycom settings (Auto-Non-
Polycom and Disc-Non-Polycom) are not compatible with Polycom telephones and
are compatible with Cisco and Linksys telephones. The setting None disables the
automatic provisioning and discovery modes of Evolution.
