• Audio ports
◦ Start Media Port (default: 16384)
◦ Stop Media Port (default: 32766)
• Video ports
◦ Start Video RTP Port

The following rules apply when configuring the video port fields:
After the Start Video RTP Port and Stop Video RTP Port are configured, the phone uses ports within the video
port range for video traffic. The audio traffic uses the media ports.
If the audio and video port ranges overlap, the overlapped ports carry both audio and video traffic. If the video
port range is not configured correctly, the phone uses the configured audio ports for both audio and video
traffic.
For more information, see the documentation for your particular Cisco Unified Communications Manager
release.
