It can be very jarring when somebody is called out of the blue and they are not expecting it. They might be deep in a task or talking to a client and by calling them their focus is getting disrupted.
Before calling someone, be sure not to just say 'hello'.
A good way to initiate a call is to warm them up by giving a warning (e.g. “Calling you in 1 min to talk about the Northwind production site being down 💀.”).
Hot Calling
The only good reason not to give a warning before calling is when the person is already expecting your pre-arranged call..
Warning: First check the persons Teams status is not "Do not Disturb", "Presenting", or "On a call" make sure not to call them unless it's a high priority item or a scheduled meeting. E.g. a Sprint Review

If the conversation has history, like a PBI/Issue or email, then it's important to include the context.

If you need to give more context than just text, sending a screenshot is a good option. If your call relates to an email, include the subject line.

Subject: "Warn then call" rule - add good example
Hi Hark,
As per our conversation,
✅ Figure: Good example - Forwarding then copying an email includes context by sharing the email and providing participant details
If you want to be extra clear, include the email with thread participants or a link to the email, especially when the thread includes multiple people or has similar subjects.
Outlook can do some of the heavy lifting for you! You can directly paste an email into a teams message with one click.
Figure: In Outlook | Share to Teams
✅ Figure: Good example - Includes a task, and gives context by sharing the email to a teams chat using Outlook | Share to Teams
When a call is declined, it is important to follow up in order to ensure the task remains a priority and does not get forgotten. You should follow up twice after the first call.
"Tried to call - will try again in 1 hour"
✅ Figure: Good example - Send them a message indicating you will try again later
Tip: The follow-up effectively rule will help you remember to call.
If you still couldn't get hold of the person, and a decision needs to be made (aka blocked), you should write your recommendation, get a cross-approval and inform them.
"Tried to call with no luck. Since I'm ❌ blocked, I will move ahead with {{ THE RECOMMENDATION }} tomorrow. (checked by {{ APPROVER }}).
Please get back to me if you prefer another way."
✅ Figure: Good example - Send them a message explaining how the next steps will move forward
