ATA Installations at multiple Starbucks locations in Colorado

We were hired to install ATA devices at multiple Starbucks locations from Fort Collins to Colorado Springs. It was our job to connect the device and the analog phone, and to test the inbound and outbound calls. We connected the ATA device to the switch/router, confirmed the link lighting was green, the power supply was connected and providing power, and confirmed the unit received dhcp address/network connection.
