SIP blocked

[koos147]

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.
