Who called from 2155738622

I missed the call, redialed the number one minute later, and got a message saying that the number had been disconnected.

This is the University of Pennsylvania telemarketer seeking alumni donations.

Thanks for the helpful info

I got a call from 215-573-8622 this number a min later i called back and there was a recoring that said this number is no longer in service

I got a call from this number of a few people laughing and then they hung up.  Sounds like they were dialing me off the Upenn alumni list (based on above comments) and then hung up because they weren't ready to talk.  A little unprofessional if you ask me!
