This varies based on the number and class of servers utilized as well as the range of devices and UC client applications utilized. 2. Stations are SIP based line registrations, hard or soft, including IP Phones and analog phones connected through a media gateway. Trunks are per bearer channel registra- tions, hard or soft, including tie lines and PSTN connections of various types including analogue, digital and SIP based. 3. Mobility calls are calls to/from outside phone numbers, assigned to users, either on the PSTN or on another PBX connected over a tie-line. 4. This varies based on the class of servers utilized as well as the quantity of UC client applications hosted per server, the amount of reserve capacity set aside for fail over scenarios, among others. > RFC2833 > RFC3261 > RFC326210 > RFC3263 > RFC3264 > RFC3265 > RFC3311 > RFC3325 > RFC3326 > RFC3428 > RFC3515 > RFC3581 > RFC3665 > RFC3725 > RFC3842 > RFC3891 > RFC4028 > RFC4411 > RFC4412 5. In case of a redundant multi node network, capacity is reserved for fail-over purposes. If one node fails, lines can be spread over the other nodes. In case of “n” nodes, each node can have a primary capacity of ((n-1)*6.000)/n lines, while each backup node will reserve 6000/n lines on behalf of a fail over situation. Examples: - 2 nodes can support 3.000 primary lines while 3.000 lines will be reserved for fail-over purposes. - 11 nodes in a redundant network can support 5.455 primary lines and has 545 lines reserved for a fail over situation. 6.
