Today a Cisco DPQ3912 telephony modem was installed on my computer and my telephone now connects to Cox phone service via that modem.
Heretofore I have always powered off my pc, modem, and router at night and restarted all in the morning.
Now I’m thinking that if I power off the new modem at night I won’t have a phone connection over night. Is this correct? Does this modem (which does not have a battery backup) have to be powered on all the time in order to have a phone connection?
