Plan Your Configuration
The EdgeMarc 4562 can be deployed as a gateway router in a network. It can also be deployed
in a network behind an existing firewall. Based on your deployment criteria, consult the following
documents for further configuration:
•
EdgeMarc 4500 Series Converged Networking Router Installation Guide
•
VoIP Operating System (VOS) for EdgeMarc User Manual
Helpful Hints
Although not recommended, the 4562 and IP phones can be installed behind an existing
enterprise firewall. In this instance the firewall will have to be configured to allow access to and
from the 4562’s public IP address for the following ports:
Port Type
Firewall Ports to Open
UDP
161 (SNMP) and 162
(SNMPTRAP)
RTP
1056 to 1255
TCP
SSH TCP 22 for remote management & TCP 80 for WAN
configuration-downloads
Telnet
23
FTP
TCP 21 for stateful TCP-session control from 4500 to Edgewater
FTP server
MGCP
2427, 2429, 2432, and 2727
NTP
123
SIP
5060 and 5075
IP phones normally point to a local NTP server for their time reference. The NTP port 123
needs to be opened if your network does not have an NTP server.
Please Note: Traffic shaping for this configuration is only available if the enterprise data
devices are also installed behind the 4500.
