Cisco Ip Phone 8800 Series Administration Guide For Cisco Unified Communications Manager - Cisco 8800 Series Administration Manual

Phone Feature Configuration
The following fields control the port ranges in the Cisco Unified Communications Manager Administration:
• Audio ports
• Video ports
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.
