The article covers the issues during realizing an auto-testing system on the VoBB (Voice over Broadband) service quality from the edge view. We give a brief introduction on the architecture of the VoBB system and find out the way to estimate the KPI (Key Performance Indicator) from the client view as well as some trouble shooting experience. With the help of the SIP based soft phone module, we can deploy the remote testing units quickly and widely without the sacrifice of large cost. This auto-testing system can work under the commercial environment to measure the streaming quality of the VoBB service and inform the related maintenance men once the service quality degrades.
