All respondents said yes
Most sites planning further installations
One site is planning to replace other videoconferencing technologies with AG
20 September 2006 16All Hands Meeting 2006
The Message in a Nutshell

In almost all cases, this means problems connecting and problems with audio
20 September 2006 17All Hands Meeting 2006
What Goes Wrong?
Symptoms Causes Solutions
Break-up, loss of connection
Network congestion, other network problems
Hardware faults
No real solution; QoS?; NB: inSORS clients more resilient to network loss than AGTk clients
Repair/replace hardware
Echo Mics too near speakers
Poor settings
Dying/dead batteries in wireless mics
Move the mics/speakers
Correct the settings
Replace batteries
Extraneous noises: hissing, crackling, general poor quality
Poor settings
Ambient room noises (e.g. aircon)
Hardware faults
Correct the settings
Reconfigure room
Repair/replace hardware
