I am trying to register 2 i2004 phones over internet. The phones register, but no voice path. when the phone registers, it throws an alarm in BCM50 alarm monitor "No public media address avaialbe for ip set" Anyone know what this is telling me? HELP!
 
Without any details from you this is only a guess:

Your BCM50 has a public IP and the IP sets are behind a NAT router. When they register to the BCM, they are registering their PRIVATE IP (likely 192.168.X.Y). The BCM knows that it can't route those IP addresses, so it shoots up an alarm.

Am I close in my guestimate of your setup?
 
Magna - you are close, but i think maybe on the right track. The BCM50 has a private address. The DSL modem/router it is connected to has the public address that the IP phone is pointed to. There is then port forwarding to the BCM50. The IP phone is definately registering with a private IP address from the home network. Since it is a base 50, I can't do any routing from the 50.
 
I've said it before, I'll say it again.

/STEPS UP ONTO SOAPBOX

Instead of trying to save a few hundred bucks, get a VPN setup and avoid the countless hours f***ing around with port-forwarding, NAT issues, no QoS etc and pulled out hair.

VPN works. Other methods can be dragged kicking and screaming into a functional state.

Bncwesty,
I setup a BCM50 with 5 ip2004 at an off site location, I used two Netgear ProSafe VPN firewall routers (FVS114, 129.00 bucks each) between the sites. I used the VPN wizard using the defaults and it worked fine.You must make sure each LAN side has a different subnet, one is 10.10.10.0 the other 192.168.1.1 as an example. If you do not have a static IP address's you can go to dyndns.org and setup an automatic update of your routers IP address( first one is free). The Netgear router, has a feature, that will contact dyndns.org every 29 days and reset the service for another free 30 days of use. Just sign up at dyndns.org. Also Netgear tech support will help you with setup. Be advised that both location existing routers will be removed and the Netgear's will replace them.
