You should now have a solid green power light, and also a solid green Internet light, If
not you must correct the problem with the DHCP before proceeding.
2.5 Router
Your router should be set up to perform NAT (Network Address Translation) and act as a
DHCP server (or have a standalone DHCP server somewhere on you network). These
features are normally enabled by default on most routers.
An IP address will be allocated to the phone automatically when you plug the Ethernet
cable from your phone into your router.
Please note: you should ensure the following ports are not blocked by the firewall within
your router:
Far end ports
o UDP Ports 4144 and 4244
o UDP Ports 10000 to 32767
o HTPPS Port 443
o Sys Log Port 514
o HTTP Port 80
o DNS Port 53
o NTP Port 123
Local ports
Outbound requests to standard services will be from a random port (as for a PC)
The following ports will be used to receive SIP and RTP packets
o UDP Ports 5061 and 5062
o UDP Ports 4241 to 4280
o UDP Ports 10000 to 32767
It is our strong recommendation to minimise the number of firewall rules required on the
router. This will reduce the CPU load on the router and also future proof the site from
future additions to the service.
This can be simply implemented by a single rule which allows all (UDP and TCP) traffic to
and from 154.51.129.0 netmask 255.255.255.0 - this is a /24 network
The system can support both static and dynamic IP addresses.
