ANNEXE D: 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 router+firewall (gateway), three indications related to the
ports used by the unit must be taken into account:
1 - Output permissions in router+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:
UDP 53 DNS protocol (servers names resolution)
UDP 162 SNMP Traps protocol (alarms)
UDP from 5004 to 5010 (it may vary) RTP protocol (audio packets towards the remote unit,
ports depend on the remote unit network, not Phoenix
one)
UDP 3478 and 3479 STUN protocol (server for getting the public IP of the
private network)
UDP from 5060 to 5062 (it may vary) SIP protocol (SIP signalling packets, port depends on
the remote unit network, not Phoenix one)
UDP 50000 to 60000 VUmeters protocol (only when remote control PC is not
in Phoenix network)
TCP 4422 (it may vary) 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 router+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:
UDP 161 SNMP protocol (monitoring)
UDP from 5004 to 5010 (it may vary) RTP protocol (audio packet toward the remote unit,
ports depend on Phoenix configuration)
UDP from 5060 to 5062 SIP protocol (SIP signalling packets)
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 router+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).
