  • PDF

Many of our Clients have the same Question! How can I Configure my Firewall/Router to use VoIP Telephony?

When we use firewall to protect your network but the same time we need to use the voip technology you must have open some necessary Ip ports

Port 5060 TCP and UDP
Port 5004 UDP
Port 3478/9 UDP for stun Server
 Ports 16348 - 32768 UDP (RTP, RTCP multimedia Streaming)

Dont Forget that the VoIP Quality has to do also with the Traffic of your Network. We Suggest you enable the Quality of Service (QoS) for the Sip Packets. The most Routers/Firewalls now Support this Feature.
