SIP blocked

  • Hey

    i have tried to replace my existing firewall with PFsense

    I was surprised my voip phones outside the network didn't work anymore (they register but there is no sound)
    when i google this i found out i need to install a voip gateway on pfsense

    is it true that the only solution is to install the voip gateway?
    i use a asterisk server behind the firewall

    i want a normal port forwarding for this just like any other firewall solution would allow me to do

  • More than likely this is due to the RTP packets port numbers being changed.

    May get you started…
