Extend Mitel 5000 System Across VPN

[bmcgonigle]

We're in the process of extending our Mitel 5000 system across a site to site VPN but there are some questions with what I hope are easy answers. Setup is currently as such:

Mitel 5000 controller in HQ (192.168.1.xxx)
Domain Controller in HQ is handling DHCP for phones at HQ. 192.168.1.0/24
Site to Site VPN to branch office with NAT and voice QOS configured
Domain Controller in branch location handling DHCP. 192.168.4.0/24

We are using 5330e IP phones for deployment.

Questions:
How should the IP phones be configured with static info?
What should the QOS tolerances be?

Thanks for any insight on this.

bmcgonigle,

Why wouldn't you just use the DHCP from the DC at the remote site for the IP Phones? All you need to do is setup a Voice VLAN and let the DC issue out DHCP to those phones with option 125.

As for QoS over layer 2 it would be 5 or 6 depending on your switch; cisco=5, HP=6. Then for Layer 3 it needs to be 46 or whatever Expedited Forwarding is for your Layer 3; I believe that hex is 128.

Thanks,

TE

Thanks for the feedback and direction. I'll do some research on the vlan/opt 125 setup. The unit in the branch office is a SMB server so I hope it allows for this configuration.

Another question: with regards to the routing of the PC ip through the phone, would this cause conflict with anything?

Thanks again,

bmcgonigle,

The PC port on the Phone only works on the Native VLAN of the port on the switch it is attached to; no routing conflicts between VLANs.

Thanks,
