Question - I can't get into the router where the ip office is located. It is owned by the provider and not in bridge mode so I need to have them access the router and make changes. Do I need to have them forward port 80 to the phone system IP address for the remote phone to access? or is it just done with the UDP and TCP ports that they already opened up.

What release, and what phone are we talking about?

ip office rel 11, remote phone 9621g

I'm getting conflicting info on the remote ip phone. the call server setting s/b the ip address of the KSU? the router S/B the address of the router hooked up to the remote phone? the HTTP S/B the public Ip address of the of the router hooked up to the KSU? doesn't sound right.

All I'm getting is "discover ( public ip address of main router ).

1) enable remote worker on the Lan port that is used for this
2) set up stun if the IPO is not connected to internet without NAT (NAT -> STUN)
3) enable remote worker on the used extension
4) enable remote worker on the user.
Then on the phone turn off 801.q (important)
Set the external IP address on the phone.
Be sure that these ports below are forwarded to the IPO
1719 UDP
1720 TCP
RTP ports configured on the LAN port (remote worker part)
ICMP must be enabled for the public IP address used for the remote worker.

Mongo - thanks for the input. Did all of the above and checked it at least twice. Still getting the "discover" message. I hooked the phone up on the same network as the ipoffice and it works fine. got to be something in the firewall

Should the Http address be the public ip of the router hooked up to the ipoffice? and the phone server s/b the internal ip address of the ip office?

Yes, simply pugging it in at home wont work. You need to enter the http/https file server for the WAN IP...i would clear the phone first...

Also, if you have TLS enabled, which you should at a minimum, i would recommend a 3rd party certificate...

That's what I'm referring to, the settings on the phone when it boots up and you enter programming. the Call Server s/b set to the ip address of the ip offfice? and the HTTP setting should be the Router address that the ipoffice is connected to?

When I plug the phone into the network that the ipoffice is on it works fine. It's just not working when using it at a remote location.

Yes, you enter the WAN IP. You only need to add to http/https, not call server.

Settings file must be autogenerated, STUN set properly etc. IDiscover means that the phone cant see call server.

That's what I thought. What would cause it not to see the call server, settings on the ip office? or the router not allowing it to pass to the ipoffice?

You need all the settings, STUN, firewall rules, IP routes etc...or you can get that error.
Look at the loge and that will lead you down the proper path.

ok, got to the screen on the phone where you enter the extension and password, I enter both then it says "discover ( IP address of call server)". If its requesting a password is it not communicating with the ipoffice?

making progress - now it says registering but that is it?

Now you will need to watch Monitor to see what/why its failing...

It was the damn STUN server! I guess I was using a bad one. It would return a value of 0.0.0.0 for the ip address. I just filled it in with what I know the IP address to be. Did not realize it was getting other info to allow call processing. What a waste of 4 days. But now I know the steps to processing a call - thanks Mongo!
