Jasmin - yes, the calls can be traced, but it's possible the Fort Collins dispatch center can't trace the calls themselves. They might require the relay company to trace the calls internally, or they may need an outside agency to help them. Either way, it is thier job to prove your are doing what they claim, and if they can't prove it, they ought to shut up. I suggest you contact the Colorado Bar Association for referral to a lawyer who specializes in Police Harassment cases - I would hope they are not harassing you deliberately - that they honestly believe what they are saying - and all they need is for your lawyers to show them where they are mistaken and they will stop. Fort Collins is not a tiny town - you can't be the only deaf/hoh person there that would use relay.
