IP Phones and VLANS

[dibthree]

We have a BCM50 (R1 fully patched) using 18 IP phones (combination of i2002s, i2004s, & i2007s) (0 digital)

We have 2 VLANS : VLAN1 = Data(we are running a DHCP srver on VLAN1); VLAN2 = Voice (BCM50 is our DHCP server on VLAN2)

When phones are plugged directly into VLAN2 everything works great.

Problem 1: If we have a situation where we need to have a phone on VLAN1 how do we set it up so that the phone will cross the VLANS to communicate with the BCM50.

Problem 2: If we plug a phone into VLAN1 and hit configuration during startup of the phone before it will let us go into setup it asks us for a password. It is not the registration password. This is immediately after hitting configuration on the i2007 or the 4 key sequence when Nortel Networks appears on the screen with i2002 & i2004. Before we can get to the screen where it asks whether or not our DHCP is None, Full, or Partial it asks for a password. Because the phone is on a different VLAN than the phone system it is not the phone system telling the phone to prompt us for a password. What causes this to happen? What would the password be?

Problem 3: Remote site has a permanent data VPN for computer file sharing. Because it is for data the VPN is connected to VLAN1. How would a phone at the remote site use this VPN connection to connect to the BCM? (by solving number 1 we will probably solve this one too)

If you have a Layer 3 switch that the phones are plugged into, then you you can enable routing on it, and allow the switch to be the def gateway for the VLAN1 phone.
(assuming you also have a different DHCP server on VLAN1)

If u don't have a L3 switch, you will need to use a router to connect the two VLANs.

I hope this is helpful.

If you had a DHCP server capable of "telling" the IP phones where to look up for their server you could solve this problem. I have a newtork divided with VLANs, but only one DHCP server with two different ethernet cards. Each one of these cards belongs to a VLAN (One for voice, one for data). I am using in this DHCP server the ENDIAN firewall. This Software lets me introduce a script for the Nortel IP Phones - similar to the way it does the BCM -. This Script contains the information about the Default Gateway, The Server IP address, the port and the action to be taken by the IP phones. Does this give you an idea?.
