Secure conferencing allows a conference resource to be set up that uses encryption (SRTP).
To configure a conference resource for secure conferencing, perform the following:
Navigate to the conference bridge configuration page (Media Resources | Conference Bridge).
Click on Add New.
From the Conference Bridge Type drop-down, select Cisco IOS Enhanced Conference Bridge.
Specify the Conference Bridge Name.
Specify the Device Pool.
From the Device Security Mode drop-down, select Encrypted Conference Bridge.
Click on Save.
Secure conferencing requires configuration on both the Unified Communications Manager and the IOS device itself. However, once configured, the Unified Communications Manager will set up encrypted RTP traffic for all devices connected to the conference. It is important that the conference bridge type is IOS Enhanced with the security mode set to Encrypted.
