      What firewall ports do you need to open to allow a Linksys SPA9000 phone system to communicate? To enable the Linksys SPA9000 phone system, you need to enable the ports specified in your Linksys SPA900 web interface. These ports can be found in the web Interface under the Voice tab, then on the SIP tab. Specifically, you need the range listed from “RTP Port Min:” to “RTP Port Max:” (TCP and UDP) and also the range from “SIP TCP Port Min:” to “SIP TCP Port Max:”. You may also need ports 8060 to 8065 (UDP and TCP).
