Excessively Low
Problem
When subscribers talk on the eSpace 6805, the voice heard is excessively low.

Solution
The volumes of the eSpace 6805 include the microphone volume of the IP phone, hand-free
speaker volume, earphone volume, and microphone volume of the earphone. The preceding
volumes are output volumes and the microphone volume of the earphone is the input volume.
