Mediation server requirements

The CS 1000 can process up to 13 000 simultaneous calls. Therefore, you may require several Mediation servers for one CS 1000. To correctly deploy OCS 2007 to interwork with the CS 1000, you must correctly engineer the network to handle the anticipated call traffic. Calculate the anticipated call traffic for the CS 1000 using the instructions in Communication Server 1000E Planning and Engineering (NN43041-220). For more information on hardware requirements, see Table 7 "Mediation Server hardware requirements" (page 53).

Signaling Server requirements

The maximum number of SIP CTI (TR/87) users on a single Signaling Server is 5000. One Signaling server can support up to 1800 SIP trunks; therefore, you require up to two Mediation servers for a single Signaling Server. To increase the system capacity, associate a pool of Mediation Servers with each Call Server. MCM routes inbound calls from the Signaling Server to the appropriate Mediation Server within the Mediation Server pool.
