MiVoice Office 250/Mitel 5000 / Cannot break dialtone
« on: November 19, 2018, 03:26:28 PM »
We have an Office 250 HX V6.3 that occasionally cannot break dialtone. Once the system is reset it works fine for a few days. Comcast is the service provider, we have verified polarity is correct. All four lines in the controller and two on the LSM are affected. We've ran Hybrid Balance and Loop Loss tests but it keeps happening.
