The calling parties experienced strange sounding voices and a very noisy connection. I started a chat with Shaw support and we did a modem reset.
According to the Arris modem info:
(Hardware Information - Arris TM602 Phone Terminal ) Solid Orange Light: Indicates that A/C power is available. If flashing, this indicates that the Digital Phone Terminal is operating in battery power.
My modem shows a solid green light for Battery.
Is this an issue or just a newer version? Model: ArrisTM602G/115
