Hi Brian, Most schools keep voice & data on separate VLANs, but do you route them separately also? The feedback I've received is mixed. Some schools do & some don't, though several that don't have said they wish they did virtual routing to keep the traffic separate at L3. Thanks. -John On 3/24/17 11:39 AM, Brian T. Huntley wrote:
We've run a converged network for over a decade. QoS can be a challenge, especially if you have a heterogeneous hardware config on your network, but running your VoIP over a separate vlan on your data net shouldn't be a problem. For us, anything considered "life safety" uses POTS lines. Our network simply isn't engineered with sufficient redundancy to make it life-safety worthy. Brian -- Brian T.

The one thing to the keep in mind is the stability of your data network, i.e. layer 2-3. Any issues will shut down your phones and that might be considered a safety issue (i.e. 911 for dorms) depending on where you are located.

We're having a debate about how to best route voice traffic over our data network. Right now, we have a physically separate data & voice infrastructure, but want to consolidate for cost savings. How many schools are using virtual routing to separate voice & data over a common network infrastructure? How many are running both without any routing separation, except for voice VLANs? Why? Inquiring minds want to know... :-) Thanks. -John -- John Center Villanova University
