Calling - Do you IM your contact to see if they’re free before you try calling them?

Always try to ping someone on IM first with "can I call you now?", because they might be with a client, or in a session.
The exception to this rule is when you're blocked and cannot proceed with a task without speaking to them.
Do you feel this rule needs an update?
