I've installed uncountable Nortel key systems, and a couple of DSX40's, but yesterday I did my first SL1100. Still learning the NEC features and terms, etc..

My customer wants to see the amount of time he has spent on a phone call. Literature indicates this feature is available, but I don't find it in the list of features in 15-07, or perhaps I don't need a button for this, just look at the display? Is there a way to see call length after hanging up?

Thanks.
Jim
