SolarWinds VoIP and Network Quality Manager uses four different license types and is licensed on the IP SLA site level, the IP Phone level, and the node level.
The following license types are available:
Any device that has at least one monitored operation counts toward your IP SLA site count.
Any IP phone connected to your network when the network is polled counts toward your IP phone count. Phones can be registered or unregistered. Registered phones are connected, take precedence over unregistered phones, and count toward your license. Unregistered phones are disconnected and do not count toward your license. If you have more registered IP phones than the number granted to you by your license, only the latest registered phones will be monitored, up to the number of phones granted by your license. Registered and unregistered phones after that number will not be monitored.
Any SNMP-enabled device that you monitor counts toward your node count. Each monitored call manager typically consumes a node license.
Each source node counts towards your node count. In a bidirectional setup, each node is both a source and target node, and they both count towards your license.
If your network uses four IP SLA sites, 45 nodes, and 700 IP Phones, you may decide to purchase the smallest license.
The number of IP SLA sites fall within your license count, but the number of nodes and IP Phones do not. When you configure SolarWinds VoIP and Network Quality Manager, you must choose 40 out of your 45 nodes to monitor, including the call managers you want to monitor. SolarWinds VoIP and Network Quality Manager automatically monitors only 300 registered IP Phones at a time of the 700 on your network. Each time your network is polled, a different 300 registered IP Phones may be monitored.
