SIP-ALG needs to be disabled as well as all other mechanisms (H323) that alter SIP traffic, SIP headers, and SIP SDP information.

SIP bi-directional traffic needs to be allowed on UDP/TCP ports 5060-5061, and 5161

RTP bi-directional traffic needs to be allowed on UDP ports 12000-32000

DNS queries need to be allowed from the phones to the Internet (UDP 53)

HTTP (TCP Port 80) is required for Mango phones to download their configuration files.

DHCP is required for any Mango devices on-premise. If you need static IP addresses, we recommend using DHCP reservations. Otherwise, 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 SBCs should be below 70 ms, but below 50 ms is recommended. 

Mango Phones must bypass all firewall advanced security features (IPS/Content Filtering/Etc.) These processes have been shown to cause issues with voice quality and connectivity.

An 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.
