  • Software Conference Bridge
  • Hardware Conference Bridge
  • Regions
  • Transcoders

Software Conference Bridge

  1. Enable the Cisco IP Voice Media Streaming App service (Serviceability)
  2. The software conference bridge will already be within CUCM and should be registered
  3. Ensure the Softkey template applied to the endpoints is Standard User for Conference softkeys
  4. Initate a conference and verify members using the ‘ConfList’ softkey

**Software conference bridge is limited to G.711
