She calls me I go through the dialog and end it, she then 'calls' back but says nothing, leaving me stuck in the call. Can't talk to people because I'm in a call thus not able to progress, anyone got fix?
All you need to do is to go to Judy/Panam (or another character that calls you). For fast travel call someone from the journal with tasks: it will be easier and faster to get there, because all the restrictions of a call will disappear.
Here i have a video, but on Russian.
