need help finding way to call US numbers from abroad

I am an American currently living in Indonesia. I need to call my bank in the U.S. to work out a problem I am having. Up until now, I have been able to use Skype to call 1-800 numbers in the U.S., but as of last week, Skype is dead. I am now looking for an alternative method.

I read online that all Skype features have been moved to Microsoft Teams, but I do not see any option in the Teams app to make phone calls. Am I missing something? If this is not possible, do you know of any alternative methods to call U.S. numbers from international?

edit: ended up using boraphone
