EMTA Battery Replacement for CA, OR and WA

• Digital phone service requires a working telephony modem (EMTA) and power to the device in order to function

• Power outages can possibly cause disruption to phone service 

• EMTAs use a battery that keep phone service functioning for 3-8 hours (depending on use and age of the battery)

• Request a free-self install kit (residential only) when the installed EMTA does not have a battery installed
   
  • Kits include information about how our phone service works in a power outage and our telephony modem batteries
     
• Cordless phones also require electrical power to their base to function. Having at least one landline phone just in the event of a power failure is recommended
   
  • If an emergency alert system requires a landline phone (such as Life Alert) that system does not work if the phone service is not working
     
    • Having a charged battery back-up or another secondary power source, as well as alternative methods of communication, such as a cell phone for emergency situations is recommended

Free Cloud Phone App is available with home phone service on any WiFi connection through a mobile device
