Appendix A: Questions to Ask When
Purchasing an IP PBX
When shopping for an IP PBX, consider asking these key questions
to brand sales representative(s):
• What is the procurement process? Can the IP PBX be purchased
directly online through a distributor? Does a reseller need to
purchase and install the system?
• What is the installation process? How many steps does it take
to get the IP PBX up and running? How much of the process is
automatic versus manual?
• When adds, moves and changes are required based on business
fluctuations, what is the provisioning process for making those
changes with endpoint devices and features?
• When firmware updates are available from the manufacturer,
what is the process for being notified and for completing the
updates?
• What voice and video codecs are supported?
• How many lines, stations and concurrent calls are supported?
• What location considerations need to be addressed when in-
stalling the VoIP system? Is the system rack mounted, desktop
or wall mounted? How many systems can be daisy-chained for
increased capacity?
• Does ongoing maintenance and administration of the IP PBX
and its devices require outside assistance from a reseller part-
ner or can it be done internally?
• Are system updates handled on-site or can updates be done
remotely?
• How easy and descriptive is the web user interface?
