Confirming the news to the Official Club Website, Trotter said: "I spoke to the manager and he said he wanted me to stay here which was obviously a big boost for me.
"I'll admit I was a bit surprised. At the end of last season I thought I would be moving on from Ipswich. I enjoyed my time at Scunthorpe and their manager wanted me to go there.
"But with a new manager here, it's a fresh start. The manager has said I'll get the chance to show what I can do and that's probably the major factor in me staying. I've not really progressed at Ipswich over the last year or two but this is a new opportunity for me."
