How to Configure Voice Vlan and vlan Routing with Data Vlan?

Dear All,

I am very new for IP telephony (VoIP).

We have topology like shown in attached dia. At this moment we have physically seperate Topology for VoIP.

Now we want to use using Voice Vlan.]


Can you guide me how it is possible?

1. Where should I create Voice Vlan? As I need to use Voice Vlan from Every location. So it can be accessible from every where.

2. What should be the configuration  on SW to SW trunk?

3. Should I use Voice Vlan in each segment? How? can you guide me for configuration?

or Please guide how should I proceed.

Re: How to Configure Voice Vlan and vlan Routing with Data Vlan?

This scenario lacks many details but I can make some assumptions. If you want a single voice vlan for both sites, then either the access switches or the L3 switches need a trunk port between them and a single voice vlan created in both L3 and access SW's.  If you can not do a trunk port between sites, then create a seperate voice vlan on eace pair of switches (access and L3 respectively)

1. Create  voice vlan x in L3 SW1 and access SW1.

2. Creat voice vlan y in L3 SW2 and access SW2.

3. Terminate an IP address from your new pool on the " interface vlan x/y" in the L3 SW's, this should serve as the default gateway for the phones.

4. Add  "switchport voice vlan x/y"  to each port on the access SW's that need a phone attached to it.

5. All routes should be updated for your voice gateways and call servers to get to your phones.

This is the basics and assumes you are using Cisco as indicated in your diagram.
