APPENDIX C: Ports used by PHOENIX equipment.
When Phoenix unit is installed in a private IP network and you want to establish communication
with other units through that network firewall (gateway), three indications related to the
ports used by the unit must be taken into account:
1 - Output permissions in firewall.
Phoenix unit will send packets to different servers and/or other units (each one will use a
different port). Therefore, firewall will have to allow that packets from Phoenix unit IP are sent
towards the following ports:
Protocol
Port number
Usage
UDP
53
DNS (domain name server) protocol
UDP
162
SNMP Traps port
UDP
5004-5010
(may change)
RTP protocol (audio packets going towards the remote
unit, ports depend on the remote unit network, not
Phoenix one)
UDP
3478-3479
STUN protocol (server for getting the public IP of the
private network)
UDP
5060-5062
SIP protocol (SIP signalling packets, port depens on the
remote unit network, not Phoenix network)
UDP
50000-60000
Vumeters protocol (only when remote control PC is not
in Phoenix network)
TCP
4422
Remote control protocol (only when Phoenix must be
connected to PC and PC is not in its network. Port
depends on PC, not on Phoenix)
2 - Input permissions in firewall.
Phoenix unit will have to be able to receive packets from units installed out of the private
network. Therefore, firewall will have to allow that packets sent to Phoenix unit IP to the
following ports are received:
Protocol
Port number
Usage
UDP
161
SNMP protocol (monitoring)
UDP
5004-5010
(may change)
RTP protocol (audio packets towards the remote unit,
ports depend on Phoenix configuration)
UDP
5060-5062
SIP protocol (SIP signaling packets, port depends on
the remote unit network, not Phoenix network)
TCP
80
HTTP protocol (only when PC must be connected to
Phoenix web server for a firmware upgrading, for
instance)
TCP
4422
Remote control protocol (only when PC must be
connected to Phoenix and PC is not in its network)
3 - When firewall uses NAT translation between private and public addresses, then a
Port Forwarding must be made in the router for each one of the ports described in section 2 and
for each one of the IPs of Phoenix units installed in that private network. In that case, remote
unit will send its packets towards router IP (it’s a public IP) and the ports configured in router by
means of Port Forwarding (these are public ports), not to each Phoenix ports (these are private
ports).
