In my personal opinion, if you need to set aside 15 minutes per day, killing at least 45 mins of productivity, for people to communicate, then your communication processes are broken. All of the things you mention could be communicated throughout the day in a team chat room. If someone needs help, they should send up a flare immediately via email or chat and get assistance as soon as someone is free.

In my personal experience, standups are practically useless if you have a team that has good communication practices. You know what people are working on from the ticket system, things are shared throughout the day as people work on chat, and if you do need some level of daily status report, having everyone email one in directly to the manager is the most efficient route.
