GoToConnect GoToMeeting GoToRoom Data center connection
Looking for the closest datacenter to ensure the quickest connection and best possible call quality.
Available data centers: list-of-supported-datacenter-provided-dynamically.
DNS SRV Lookup GoToConnect's SIP servers are discovered using SRV lookups. Your DNS server needs to process these appropriately.
Packet Loss Occurs when packets fail to reach their destination. A high rate of packet loss will affect call quality. We recommend a ratio less than 1 percent.
Latency To ensure the best user experience, the end-to-end latency of a VOIP system should be no more than 150 ms (including voice encoding, transport and decoding). This test measures the network latency (transport), which should be less than 100 ms.
Jitter Voice packets travelling on a network from point A to point B don't always take the same time to travel (and sometimes even arrive out of order). The jitter is a measure of the variance of packet latency. A jitter lower than 30 ms is recommended.
Bandwidth check This test checks if your network can send and receive enough data to ensure good call quality. We test downstream and upstream bandwidth (incoming and outgoing data) for a speed of up to 90 Mbps.
More bandwidth means more concurrent calls
G.729 G.711/G.722
1 call 0.008 Mbps 0.064 Mbps
5 calls 0.040 Mbps 0.320 Mbps
10 calls 0.080 Mbps 0.640 Mbps
50 calls 0.400 Mbps 3.200 Mbps
100 calls 0.800 Mbps 6.400 Mbps
ic_feedback/info_inactive
SIP ALG Stands for Application Layer Gateway, and is common in many commercial routers. This should be disabled to prevent the router from modifying SIP packets.
Open Ports Test whether ports required for normal operations are blocked.
NAT Settings NAT binding timeout is the length of time that the router still keeps an inactive UDP NAT session. We strongly recommend a delay greater than 30 sec.
