• Question 135:

  You want to deploy a mixture of unicast and multicast MOH streams. You need to configure 12 multicast streams, each supporting two codecs. How many unicast streams can be configured, assuming 250 is the maximum number of MOH streams supported on your MOH server?

  A. 204
  B. 214
  C. 226
  D. 250
  E. 202
  C. 226

  ---

  Maximum Half Duplex Streams determine the number of devices that can be placed on unicast MOH. The parameter should be set to the value derived from the following formula: (Server Capacity) - [(Number of Multicast MOH sources) x (Number of MOH codecs enabled)] 250 - [12 x 2] = 250 - 24 = 226
