VOIP phone line gets loud Buzz
Who has their ATT VOIP home line Buzzzing loudly. Ours does it at least 2 times daily. We have an optical line interface. ATT techs have been out here twice testing and replaced our router gateway. We reboot the Router gateway and it will happen again withing the hour, sometimes. We have even come off hook with POT and it was BUZZING its little heart for all it was worth. Rebooting will clear the ocurance but will do it again without notice of any other symptom. Has anyone had them solve this symptom or have a suggestion, (not to include changing carriers)?
We never had this with U-Verse but is chronic with Optical line servise.
