voice agents: G.711 mu-law, G.711 A-law, G.729, and G.729a
Audio: For video upload, MediaSense requires AAC-LD MP4A-LATM.
The audio is converted to AAC-LD MP4A-LATM, G.711 mu-Law, and G.722 for
codecs for Mobile Agent. Remote and Local ports must use the same codec.
codecs for CVP prompts. CVP prompts must all use the same codec.
For video playback,
MediaSense does not support G.711 A-Law.

The Unified CVP
VXML Browser does not support SRTP. While calls are connected to the VXML
Browser, the calls cannot use SRTP. But, calls can negotiate SRTP once the
media no longer terminates in the VXML Browser.
Deployments that use span-based silent monitoring do not support SRTP.

Outbound Option Dialers do not support SRTP. While calls are connected to the
Dialer, the calls cannot use SRTP. But, calls can negotiate SRTP once the call
is no longer connected to the Dialer.
Availability (HA) and load balancing are achieved using these solution
- Time-Division Multiplexing
(TDM) Gateway and Unified Communications Manager, which use the SIP Options
heartbeat mechanism to provide High Availability.
- Unified CVP servers, which
use the SIP server group and SIP Options heartbeat mechanism to perform High
Availability and load balancing.
