Customer Prerequisites

Cloud PBX customers need to have a reliable broadband connection that offers adequate bandwidth for your voice traffic. VOIP will tend to require anything from 24 to 88 kbps per call and as a rule of thumb, it is best to assume that you will need at least 90 kbps in both directions per concurrent call to use VoIP reliably. In other words, to support five simultaneous calls, you need 450kbits/sec (about 0.5Meg) of uncontended bandwidth, up and down.

To ensure optimum voice clarity, an enterprise standard broadband modem, with quality of service is recommended.

Smartphone apps need a stable WiFi signal for operation on the LAN and a good 3G signal for voice over IP on the public Internet.

While we offer emergency service in certain markets, it is customer responsibility to advise us of the geographic locations of all devices.

 

Hardware

All that is required is a broadband connection and a calling device (PC softphone, smartphone, desktop phone). The PBX is hosted in the cloud, so once your device has access to the Internet it registers with the switch and becomes your connected extension.

Network Router

VoIP requires routers that support QoS (Quality of Service). Easier installation is accommodated by DHCP (Dynamic Host Configuration Protocol).

IP Phones / Handsets

Desktop system phones (Executive and Professional) come pre-configured with company user and extension information. They must be powered up by plugging an associated power supply into the mains or by plugging the Ethernet cable into a Power over Ethernet (PoE) socket. They must be connected to your LAN.

Firewall

Many routers include a firewall which protects the network from malicious Internet traffic. The firewall must allow the handsets outgoing access to 5075 TCP, HTTP, HTTPS, and UDP traffic on the Internet. There is no requirement for incoming port forwarding.

Switches

Only business-class switches capable of QoS (Quality of Service) should be used. A QoS capable switch ensures high-quality audio during calls as it places priority on voice packets to and from the IP phones.
