    Has anyone been able to use a SIP phone with their RV016? I can't get anything but One way audio.

    what VOIP phone/adaptor are you using, you may need to open some ports to the phone/adaptor (port forward)

    I am not using any adapter. I have a couple of WiFi VoIP phones. One is a UTStarcom and the other is a Zyxel. Right now I am just doing some testing with SipPhone.Com. Last night their test number said that I was on a SIP Aware router. Today, it is telling me that I am behind a nat router and will have problems placing or receiving calls. Boy are they right.

    yes so what ports do they operate on? if sipphone.com does not know then they are pretty useless.

    you need to open up the ports for that phone.

    Looks like they want to see these ports open:


    I opened the ports, now it tells me I am behind a SIP compatable router. however, still no incoming calls. Also, still have one way audio. They can hear me fine, I cannot hear them. Odd however, I can hear all their test recordings on their test numbers.

    try the DMZ host setting and put the IP address of the Phone in to it. just want to see is it is a Firewall problem or not.

    Didn't work in the DMZ either. Then, I got to thinking about trying another number. I called someone's voice mail, recorded a message, deleted it, the whole nine yards. Then, I tried calling my Fax line. Perfect. There is something about my home phone that does not like getting calls from a VoIP number. I tried another VoIP service, same thing. Called the fax line, perfect. This was all on the DMZ. Now, I am going to wipe out all the firewall rules I created and start over with the Basics.

    Any idea if Port Triggering works? Or, do I need to create services and assign a rule to them?

    what make/model of phone do you have?

    The phone I have been working with the most is a ZyXEL P2000W_v2 running the latest firmware which is WV.00.04. I was also messing with an Xten Pro softphone. The ZyXEL is my main priority.

    I had a Sonic Wall firewall one time that was SIP aware, you didn't have to do anyhting and it worked. That firewall was 2-3 years old with current firmware. I am surprised that this Linksys that is two days old does not have the capability. I certainly hope I don't have to use this phone in the DMZ.
