FVS336G limit SIP server for Voip

Dear Netgear Community

We have a new VoIP solution installed together with an existing Netgear FVS336G V2.
Is there a way to configure the FVS336G V2 to limit the SIP signals to only come from the server of the VoIP provider? Where would I do this?

Thanks for your help.

 

  • Hi olig,

     

    Since your VoIP provider has suggested it then it means that it might help for the VoIP solution to function well.  Try to follow the suggestion then observe what happens.  If ever it doesn't help then you may just delete the rules then inform your VoIP provider about it.

    Hi olig,

     

    Welcome to the community! :) 

     

    Kindly answer my questions below:

     

    a. How is everything connected?  Kindly post a screenshot or image of your detailed network setup. 

    b. What is the current firmware of the FVS336Gv2?

    c. Does your VoIP provider mentioned that you need to open ports for the new VoIP solution?  If yes, what are the port numbers needed to be opened and to what IP addresses should it be opened? 

     

    I look forward to your response.

      Hi DaneA

       

      Thanks for the prompt reply.

       

      1. The setup is very simple and straightforward: Internet signal coming through a modem/router to WAN1 of the Netgear FVS336G. From there LAN1 goes to a Smart Switch which leads to the different workstations and IP phones. IP address to the outside world is fix.

      2. I’m afraid there hasn’t been an update for quite a while. Firmware – Version: 3.0.6-28

      3. The VoIP provider initially gave me the following information:

      IP range for communication WAN/LAN and LAN/WAN

      Where do I configure this?

      UDP Ports

      Done

      IP range for configuration LAN/WAN for http:// and http://

      Where do I configure this?

      TCP ports WAN to LAN and LAN to WAN

      Where do I configure this?

       

                                

      Forgive my ignorance, but would these parameters set correctly already limit the SIP signals to only come from the provider, or do we need additional settings?

       

      Thanks and regards

      Oliver

        Hi olig,

         

        I think you could configure the IP range on the Firewall LAN WAN rules.  Kindly refer to the figure on page 230 of the FVS336Gv2 reference manual here.  As you can observe, you can select IP Range on "Send to LAN Server."
