Zoiper RTP ports or voip server RTP ports

[robertkwild (robert wild)]

hi all,

i have set my RTP ports on my freepbx server and have NATed them on my opnsense firewall, 10001-20000

but going by the below, what takes precedence, the zoiper RTP ports or the ports i have actually nated in my firewall and freepbx server

saying all this i can send/recieve calls no problem ie i can hear voice which is what RTP does?

thanks,
rob

They relate to different ends, so can be completely uncorrelated. Generally your router should allow all port numbers for the remote end, and not translate them, and that tends to be the default.
