PKMN Trainer Red cannot be rematched in any game.
yup you can
To rematch trainers, look in the pokenav's trainer's eyes and if the little pokeball looking symbol appears by their name, you can rematch them by talking to them.
In order to rematch Jasmine in SoulSilver, you will need to get her Pokégear number which you can accomplish by going into the Diner in Olivine City between the in-game time of 1PM and 2PM any day of the week, Jasmine will be there so just talk to her and her number will be registered. After that, just call her on the Pokégear on Wednesday during the afternoon and she'll head off to the Dojo in Saffron City which is where you will be able to rematch her at.

It is not possible to get Red's phone number. If you want to have a rematch you must beat the Elite 4 and Champion again.
every time you beat the Elite four, red will appear at the top of Mt. Silver again
