VoIP Phone Systems

LeeShanok designs, installs, maintains and supports VoIP systems from several partners we carefully selected. The first questions we ask our clients are how many phones do you expect to need, and then do you have a single location or multiple locations?

The quantity of phones will help determine which of 3 VoIP solutions will tend to provide the best economics, and which will tend to provide the cleanest architecture we design. Phones can be leased, but at their relatively low cost we recommend purchasing the phones you’ll need. Phones with color touchscreen displays cost an additional 25% or more than phones with monochrome non-touch displays but are worth the additional cost when the desk phone is used frequently. All IP desk phones have one RJ45 port for a digital uplink CAT6 cable connection into the local LAN, and some models have a second RJ45 port to piggyback a computer through a built in network switch inside the phone, eliminating the need for a 2nd network drop near the desk. Mobile phone connectivity and soft phone apps on workstations are usually included at no added cost.

Phone Models

There are many VoIP phones available from many vendors, but we recommend Cisco and Yealink phones depending on their compatibility with the selected infrastructure model.

Infrastructure Models

VoIP Phone Systems follow 3 infrastructure models:

Cloud/Hosted

For small companies with up to 15 phones in one or more locations, we find that a Hosted (pure cloud) VoIP solution requires minimal initial cost with monthly costs based on the number of IP phones and DID extensions. We recommend the cloud hosted solution from Star2Star Communications.

Hybrid

For companies with 20 – 50 phones in one or more locations, we find a Hybrid VoIP solution provides the best mix of economics and flexibility. In a Hybrid Model, the VoIP “server” is hosted by the phone vendor in their cloud environment, but there is usually a small on-premise appliance installed inside your network, but even that is usually managed and updated by the phone vendor. For this group, phones are purchased along with the on-premise appliance, which supplies QOS call-quality management. A 4G/5G failover appliance is often recommended to keep the desk phones functioning in case of internet outage. In multi-location situations, we often recommend the appliance be installed at the main domain site, without the need to replicate that at smaller branch locations.

On-Premise

For companies with 50 or more phones, we recommend an On-Premise VoIP solution. Cisco’s Unified Communication solutions provide nearly unlimited features and configuration. In this infrastructure model, the VoIP server is physically or virtualized on-premise, providing maximum flexibility and low monthly payments, but requiring substantial initial cost and also requiring internet connectivity with substantial bandwidth requirements.

Cisco’s Unified Communication solutions scale from cloud based to on-premise and have nearly unlimited add-ons and configurable capabilities available.
