Pokemon Crystal : Forcing trainers to rematch

[Asia81]

Hello, I have the same question as this guy

https://gamefaqs.gamespot.com/boards/375087-pokemon-crystal-version/76556607

 

In order to get a 100%, I need to rematch these trainers at their strongest teams, but I don't know how can I force them to call me for a rematch.
I searched for ar codes, but found none, as well as event flags in pkhex, but I only see flags to make them already battled, and not waiting for a battle/rematch.

 

Any solutions would be appreciated.

Ok I found a workaround to trigger phone calls.

Just talk to your mom and activate/disable daylight saving time. After that a call will be generated almost 95% of the time.

I managed to get all the calls and rematchs I needed due to this manipulation.
