Feature Interactions and Limitations
This section provides a list of possible interactions and limitations to consider.
Call Recording, Whisper Page, or Service Observing is used on video calls.
In this situation, expect audio-only calls unless the ad-hoc video conferencing feature is
enabled. Each of these features counts as an audio-only participant in the call. See related
issues below.
Video endpoints are involved in conference calls, and ad-hoc video
conferencing is not enabled.
Conference calls refer to calls with more than two participants. The limitation described here
may not include calls to auxiliary devices over trunks; for example, using dedicated video
conferencing devices.
In this situation, expect audio-only calls even when only two of the endpoints are video
endpoints. To prevent this, enable ad-hoc video conferencing. There may be benefits to
enabling ad-hoc video conferencing without any ad-hoc video conference bridges. For more
information, see the related question below.
More than two video endpoints are involved in calls, and insufficient ad-hoc
video conferencing ports are available.
In this situation, expect audio-only calls. If there are no video ad-hoc video conferencing ports
available, you only receive video if there are exactly two video parties on the call. If there are
more than two video parties, no one receives video because no good rule exists for deciding
which two parties should have it. If you have exactly two video-enabled parties, you can have as
many audio-only parties as fit and you still get video.
Keep in mind that
● A call over a video-enabled trunk counts as a video party even if it is to an audio-only
endpoint.
● A call over a non-video-enabled trunk counts as a nonvideo party even if it is to a video
endpoint. This includes calls routed via IGAR and may include failover trunks.
● A video-enabled endpoint with a nonvideo endpoint registered to it, such as a
shared-control endpoint with the video IPSP logged out, does not count as a video
endpoint.
● A video endpoint with video stopped or muted still counts as a video endpoint.
● If you have video and you add a video-enabled party, you lose video.
