Problem completing call to one particular cell phone from UVerse landline
I have recently started getting a busy tone when I call one particular LG cell phone from my Uverse landline. If I call the number from my cell, the call goes through so I thought my number had accidentally gotten blocked but after the LG owner checked everything out, there is no block on my home #. I have spent hours on the phone with ATT about this and have been given the run around so far. They blame LG and LG blames ATT. I can call other cell #s with no problem and the LG owner can call my landline with no problem. My son thinks it has to be a faulty UVerse modem but I have no idea at this point. Anyone else ever have this problem? Any suggestions for a solution? I have unplugged the modem and reset it but it didn't help. My internet service is working and all of my other calls are okay. I was able to call the LG # up until the last couple of weeks with no problem.
