o If you are using an external power source plug the power supply cable into
the power port on the phone base.
NOTE. The Cisco SPA 504G does not ship with a power supply. If you are
not using Power over Ethernet (PoE), you must order the PA-100 power
supply separately.
o If you are using Power over Ethernet (PoE) to power the phone, the phone
will receive power when you connect an Ethernet cable from the phone's
Network port to a switch in your network that provides PoE.
o If you are using a headset, plug the 2.5mm jack into the port on the right
hand side of the phone.
2.3. 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
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
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.
