When installing a hosted VOIP phone system you are faced with a couple common scenarios, you can either have the VOIP phones on their own network, completely separate from your data network or you can combine the two networks, sharing infrastructure cabling and switches.
Both scenarios work perfectly fine, but there are major differences in set up, configuration and cost. In this document we will point out some of the major differences and what to expect with each scenario.
- Only one jack per workstation, phones and computers will be sharing the same connection
- Data switches will have to be configured with a separate vlan to separate the voice and data traffic
- QOS will have to be configured on router to ensure voice traffic takes priority
- No up front infrastructure costs to implement(unless switches need to be upgraded to support vlans)
- A lot of technical programming required on the customer’s data network (creating vlans, configuring QOS)
- If client is not familiar with setting this up, we may have to outsource an IT professional to help us configure the firewall/data switches to accommodate this configuration
- Much more difficult to troubleshoot issues as the client’s data network must be examined extensively, which again can involve outsourcing IT professionals
- Setting up and testing can be disruptive to the client’s network
Separate Physical Network for Phones and Computers
This requires separate jacks for phones and computers at the workstations and a separate switch for phones and computers. A separate internet connection is also recommended in this scenario.
One jack at the workstation, phone plugs into jack, computer plugs into phone.
A Vlan should be programmed into the switch to “virtually” separate the voice and data traffic on the network. Internet connection is shared with router handling the QOS.
