Narrative:
On apr/tue/97 I received an EMS flight request at about XX00 hours. I departed X helipad heading northbound. Prior to departing, I contacted aa tower, was given a squawk code and told to proceed. After crossing, aa tower said to contact B approach. Called B approach. At this time I thought I was under B control. As I was crossing runway Z at airport C, a jet was coming in on final. I descended to remain clear. After this, approximately 5 mins later, I was contacted by B approach control and advised that I needed to let them know if I was going to take the beach or shoreline departure route. My assumption was I was under B control and I did not contact C tower.
