CallManager 3.X does not have the video capability sets required for VTA that CallManager version 4 now has encoded.

Video enhancements have been made to H.323 and SCCP signaling and call processing within CallManager to allow video calls to be placed with the same user model as audio calls.
CallManager supports new video end points that will be released over the next few months.
SCCP Video endpoints inherit the functionality of audio calls which gives the user the same call model for both video and audio calls.
CallManager has the infrastructure to handle codec and video capabilities of the endpoints, bandwidth negotiation to determine if video/audio call can take place, single point of administration, management of media devices such as gateways and MCUs.
CallManager provides a common control agent for signaling, configuration, and serviceability for voice or video end points.
Planned endpoints include SCCP-controlled voice-video IP phones.
