Recommended WAN/Internet access type:
Fiber offers the most reliable and stable internet connection, usually offering faster internet speeds, less packet loss and lower latency overall, which are key elements for a great experience using VoIP.
We recommend having a backup connection in case your main internet connection fails. Backup should be delivered preferably using another internet access method like wireless, copper or coaxial.
VoIP Bandwidth Requirements:
Since PhoneIQ uses the public internet to route phone, network administrators should allocate a certain amount of bandwidth exclusively to VoIP traffic.
Voice traffic: 100 kbps per phone call (for both download and upload traffic).
E.g.: If a network admin estimates 8 simultaneous phone calls at any given time, he/she should allocate 800 kbps of upload and download bandwidth for PhoneIQ. (See Firewall settings here & QoS suggestions here).
