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.
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.
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.
