L3 Module or Router need

For an IP Telephony requirement, I plan to implement a Call Manager along with Unity voice messaging software for additional features. I have a Cat4006 switch as core switch with access gateway module.<br><br>Since I am new to this topic, I need advice on the following questions:<br><br>1. I plan to configure the Call Manager and IP phones in one vlan (voice/aux vlan), while all the PCs will be in the regular data vlan. Which VLAN should the Unity server be part of? If users need to read their email from Unity servers, right on their desk, should the Unity be in data vlan or voice vlan? If it has to be in a different vlan than the CCM, is there any need for L3 module on the switch (or say a router in the network)?<br><br>2. Can CCM and Unity be on the same hardware? OR is it a must to have them on different MCS servers?<br><br>Thanks in adv<br><br>Consultant<br>Compaq Global Services

Re: L3 Module or Router need

Yes, you need a router whenever you have two or more subnets.

Re: L3 Module or Router need

Can I use the Cat4000 Access Gateway Module for this L3 functionality? I understand from specs that the Access Gateway Module also has the IOS routing functionality.

Can anyone confirm plz...

Re: L3 Module or Router need

I can answer the second part of your question.
No, CCM and Unity cannot run on the same machine simultaneously.

Re: L3 Module or Router need

If your Unity server (mine is a Dell Poweredge 2500) has an Intel Pro/100+ Server NIC card you can download the driver (2.35.0.0) from Intel that will allow your NIC card to do 802.1Q/p trunking between the 4006 and the server. you can create virtual adapters and place them in the correct VLAN. This works great for us. It allows Unity to be in the non-routable address space and yet still have external access to it by assigning the server an IP address in the data VLAN. I wish they would put a server class card in the Call Managers so that you could do the same thing on them. We have to terminal service to a different machine then go from there to the Call Manager's because because our Voice VLAN is in a non routable address space.

Though this might help.
