I got a family member to switch to Dish but after 4 receivers dishcomm and caller id on phone line do not work. Has anyone else seen this? When scanning dishcomm i get an error telling me that dishcomm cant be scanned and i need to call Dish. the 3rd receiver they sent us worked with Dishcomm but after a few days the unit continually rebooted. I hooked up a wireless jack and i get no caller id information. Any help would be appreciated.
