That’s impossible to do. And unrealistic and unattainable expectation that police should make sure callers are certain that an imitation gun is a real gun. It is also not without risk of an untrained person ending up in a deadly confrontation with the person they are calling about.
An example is when the police asked George Zimmerman to follow a suspicious person walking through his neighbourhood who he though had a gun to “make sure”, he ended up shooting a killing an unarmed black kid by the name of Treyvon Martin who had just gone out for sweets.

The responsible advice to an untrained and unarmed person would be to get away from the location as quickly as possible.
I am not sure why you think the introduction of Trayvon Martin into this discussion in any way adds to your argument.
Surely he is the poster child for what goes wrong when racial profiling and institutionalised racism on the part of both civilians and police result in the murder of the innocent?
Just as in this case the disproportionate response of the police resulted in the victimisation of a black youth and the terrorising of his family...
There is no indication whatsoever that the boy answered the door with the gun in his hand or that he threatened the police in any way. They did not know when they arrested him if he were a younger relative of the 'black male' reported by the caller or the subject himself. If they did know he was the individual the caller reported then they must have understood that they were dealing with a child, and they did not deal proportionately with him.
If it is impossible to require that callers to the police be sure they have seen a gun and that they have reasonable concerns about the danger it presents then the police need to figure out questions to ask to flesh out the report for credibility and to determine the level of force needed in the response.
This is because the police are carrying real, loaded weapons guns, and people can and do get injured or killed by the police, and because that matters.
