If your firm is making the switch to VOIP, make sure you have an advocate for IT on the project, especially someone who has been through a VOIP migration before. If left unchecked, VOIP engineers and consultants can unknowingly run roughshod over the IT network, dictating changes and additional network services that can impart unforeseen consequences if not done correctly.

The IT advocate will protect the integrity and stability of the network and help avoid common pitfalls during a VOIP migration. He or she can:

• create an inventory of what network services would be impacted,
• point out design changes like the proper number of switches.
• properly setup and configure network services that the VOIP systems require, something a “phone guy” may be able to do, but will likely not have the experience and expertise to avoid any adverse effects that impact a pre-existing network infrastructure.

Going VOIP also means ceding some control over the network—especially in hosted VOIP services—and the IT advocate can help smooth that transition. Depending upon the type of service you select, you may lose control over vital network functions like NAT, port access translation, VPN and Citrix service redirections. (Access to internal systems you may have come to take for granted until they no longer operate properly). The IT advocate can help map out how to handle these critical services within the new environment. At the very least, an IT advocate will represent your network interests with the experience to help guide your VOIP installation in a way that will impact your existing infrastructure with as little negative effects as possible.

The company installing the VOIP system will work to provide the best phone system, but the IT advocate will make sure that it doesn’t come at the expense of network reliability, functionality and performance.
