I would probably advise against doing this. There have been rumors of Russian police looking through citizen's phones for indications that they are engaging with western viewpoints on the "special operation". And the penalty for such activities is quite high right now.
A random phone call from a U.S. citizen might look suspicious, and I don't imagine Russian police are giving much benefit of the doubt right now.
