The Mitel 5000 system (connected to via MiVoice 250) contains all of the phones. To the best of my knowledge, all of the phones were initially setup here in the main office.
We have two satellite offices, each containing one phone. The one that works has an extension in the Mitel 5000 of 12703. It is connected to a Time Warner supplied router with the following settings on the phone itself:
Static: 192.168.200.201
Subnet; 255.255.255.0
Gateway: 0.0.0.0
Remote IPS IP: 216.198.156.40
TFTP Server (I don't know what this is or if it is important): 192.168.200.202
The phone uses DHCP, acquires an IP Address and successfully routes itself to our system. I can dial the extension from the main office and the user picks up and converses just fine.
The other office has the same type of phone and, to my knowledge, was setup here in the office. I had to change the settings of the phone to match the other satellite office. The are:
Static: 192.168.200.201
Subnet; 255.255.255.0
Gateway: 0.0.0.0
Remote IPS IP: 216.198.156.40
TFTP Server (I don't know what this is or if it is important): 192.168.200.202
After some time, the phone acquires an IP Address and connects to the system. I can call the extension and can tell that a user picks up, but nothing is heard on either end.
I attempted the Copy (extension number) of the satellite phone that works and Pasted it to the one that does not. No go. I've verified all settings and they seem to match up although it is apparent that something isn't matching up.
I'm not sure about the NAT vs Native setting you are referring to.
Thanks for the help.
