presentations for voice only meetings
If you are talking about presentations for voice only meetings then perhaps sending a copy of the presentation and just saying slide X so everyone with a clue and an attention span can see the correct slide.
Alternatively you could always just do a report via email saving everyone's time. Presentations take far longer to relay information than just reading a report. Additionally for those who understand the topic and can read then reports allow you to provide the redundant waffle for those that need it i.e. managers who got their job because the boss also doesn't understand the business they are in, they are after all the only ones that think presentations are useful beyond sales.
