Has anyone been able to get a remote IP phone to work without VPN? We have a customer who went from a Prologix (CLAN & Medpro with public addresses) to an IPO. We configured LAN2 with a public address in hopes we would be able to keep the setup for the remote phones the same...point them to the public address of the IPO. It is not secure but is what they want. Any thoughts? Thank you.
 
just walk away......

Well that does not seem to be too promising? Thanks for the advice. It is a shame since I know this has been done with other systems and I know we have done it with the Definity and also with the Samsung OfficeServ. I guess we are out of luck? Thanks again for the quick responses.
 
security is different on those systems
the only half decent way to get that working would be if you know where the connection comes from and put an IP route in that goes back to that IP address on LAN2 via your gateway of that connection so that any other attempt to come in will not have a way back. Not ideal but possible because your default route will be the 0.0.0.0 with mask 0.0.0.0 to your LAN gateway and therefore behind the firewall.

I agree it's a shame you can't do it, I think the Avaya way of using a VPN connection is far from ideal and can often be more trouble than it's worth :)

Peter will go mad, but I like the Mitel way, you set the user as a NAT phone and enter the companies external address into the system NAT address field, job done, no VPN as many external users as you like without worrying about the router and no special load or settings on the handset :)

Thank you for all the support. I took the phone home and the only way I have gotten it to work is by connecting directly to my cable modem so that the phone grabs a public address. That works fine but when I put it on LAN at home it just keeps trying to discover the call server address.
 
put it on a DMZ because I doubt that someone will screw up your IP phone as it is hard enough to just get it working nevertheless try to make it do things it is not usually doing.

Update...I am able to get the phone to register from the remote LAN and I can make and receive calls but there is not audio.
 
That is because it uses different ports for that.
Try to forward the 49000 to 55000 port range.


BAZINGA!

I'm not insane, my mother had me tested!
 
No luck so far. For now I asked the broadband provider for another routable address, installed a switch off of the broadband modem and the phone (and LAN) works fine that way. I will keep trying the port forwarding suggestions. Thanks.
 
Mitel boasts heavily on their ability to uplug your phone, take it home, and it works. I wish Avaya had that same ability.

Yes it is good, but they make one big compromise to do it, they make their own type of H323 (Minet) as such only their IP phones work and you can't H323 trunk to any other kit apart from Mitel, you have to use SIP. That being said I still think it's a far better way of doing it than depending on VPN's :)
