In the calculator above you can find commonly used values for the pre-delay and the decay time. Nevertheless, the formula for seawater is even more complex as the speed of sound is also changing with the salinity. Other than the temperature, the speed of sound depends on the medium through which the sound waves travel. This is the formula: D=X/S*1000. X is the distance from the main speakers in feet. It is used to execute functions such as to recognize you when you return to the website. This is a new install with CUCM 8.5.1. This is not limited to conference calls, and those conf calls hosted externally with a single caller from this environment are having the same issue.
