I have a phone Audiovox cdm 8615BM and I can't get it to work at one place (cottage). All other cell phones work (friends) with same company I'm with. One of my friends has the same phone with same company and he brought it over to the company and they played with the settings and told him they boosted the signal just playing with the settings on the phone. his phone now works at the cottage. I went to the same place he went and they don't know how to play with the signal on the phone settings. Has anyone heard or know about settings on that phone to boost the signal?

Thanks
