Hey Guys,
Have a couple questions about the static setup. This user is on a site to site and therefor on a different vlan. Our voip vlan is 90 and her vlan is 90. I'm curios when setting up the phone what gateway she should use. Should it be the gateway of her router or the vlan 90 gateway? Also the TFTP server address should be the address of the phone system but when it ask for a TFTP port what should it use? The way I currently have it setup is with the vlan 90 gateway and no TFTP port. All other static settings are correct. Once she rebooted the phone she has on her screen DHCP option 129 missing. any help is appreciated.
There are a couple things going on here, I am not sure you understand the VLAN thing, according to what you said she is on the VoIP VLAN (90)... In the remote location there shouldn't be a VLAN at all and any VLAN tagging will likely not transpose the VPN tunnel.
First you need to verify the routing on the network the Mitel is at is configured proper... make sure from the remote location you can ping the local IP address of the 5000, if not, the remote end needs additional configuration to allow the the two VLANs to communicate with each other. Then, on the remote end, the phone should be completely default, enable DHCP on the LAN at the remote end and connect the phone, then press and hold the 7 button well the phone is booting, it will ask you to configure Teleworker mode, do so and input the internal IP address of the 5000, save and reboot... the phone should boot up and get an IP address via DHCP (and NOT want Options 43, 125, or 128+) and connect and you should be good to go. That's it. In this setup the phone isn't actually "remote" to the Mitel 5000 since it does not transpose a NAT connection.
Putting the phone in Teleworker mode tells the phone to not look for the DHCP auto-configuration options and to connect just to a specific IP address. Also, in this specific configuration, do not tell the system to NAT the phone, it should be set to Native.
