Setup ISP Router Bridged with ISP VOIP

[sphillips]

I have been trying to use ISP Modem/Router as bridged without loosing VOIP for a while but cannot figure it out.

As soon as i change the configuration on the ISP router to bridge all works fine pfsense PPPOE gets public IP and phone works no problem as long as i don't reboot the ISP Router.

Once i reboot the ISP router, pfsense PPPOE will get public ip and phone will work but after 3min it will will disconnect get new IP and phone will not work anymore, inside isp router reports that phone is online.

VOIP has static IP under vlan30
