The following network settings and recommendations will help Mango Voice customers get the most out of their VoIP service.
Internet Speed/Bandwidth needs to be at the very minimum a speed of 5 Mbps down and 1 Mbps up. We recommend a speed of 10+ Mbps down, 2+ Mbps up. The faster the internet speeds, the higher the quality of the resulting calls.
SIP ALG needs to be disabled as well as all other mechanisms that will alter SIP traffic, SIP headers, and SIP SDP information.
SIP bi-directional traffic needs to be allowed on UDP/TCP ports 5060-5061
RTP bi-directional traffic needs to be allowed on UDP ports 12000-32000
DHCP is required for any Mango devices on-premise. Static IP addresses may be used if they are set up and maintained by the customer's IT staff.
VLANs are supported but must be set up and maintained by the customer's IT staff.
Network latency to Mango's hubs should be below 70 ms, but below 50 ms is recommended.
Ethernet connection is required for each Mango device. In the case where only one ethernet outlet is available, Mango supported devices should have a built-in switch. A Mango device must be plugged in first and all other devices must be plugged in through the Mango device.
NAT is an essential part of most networks. Mango devices do support NAT traversal over a single NAT connection. Networks with double NATs are not supported and will cause undesired results.
Traffic shaping is recommended but not essential in most healthy networks. If traffic shaping is needed, all Mango devices will pass a QOS DSCP priority tag of 26 and 46 for audio and 34 for video. You can use these DSCP priority tags to prioritize voice and video traffic.
