When Kirk is on the phone with the doctor, he says they just passed Winterthur and he'll be there soon. They are supposed to be in Geneva, but Winterthur is not near Geneva, it is near Zürich. Geneva is more than 3 hours away from Winterthur when traveling by car, which is how Kirk was traveling.
Samar chases Gouldsberry and he goes into the server room. She can see him through the glass and has several clear shots at him, but she does not fire. A trained operative such as her would know the proper technique there was one shot to shatter the glass and the second one to gank the suspect. A trained agent could fire these shots in less time than he could react.
It makes no sense for Gouldsbury to leave the phone behind that he used to communicate with his next victim. She might call him for any number of normal pre-meeting reasons, as for instance, to postpone or call off the meeting, change the location, ask him for directions etc.
