Box contents
When you receive your Yealink Cisco 192 ATA, the box will contain:
- ATA (e.g. ATA191 or ATA192)
- Power adapter (if not using PoE)
- Ethernet cable
- Analogue phone (standard home or office phone)
Setup
To connect the ATA, plug one end of the ethernet cable into the network port on the ATA.
Plug the other end into your router or network switch.
Wait one or two minutes until the power and network lights are solid (not flashing).
To connect your analogue phone, plug it into the Phone 1 (Line 1) port on the back of the ATA. When you lift the handset, you should hear a dial tone.
If you have a second phone line, you can use the Phone 2 (Line 2) port
The Network or Internet light should be solid. If it’s off or flashing for more than two minutes, check the ethernet cable connections, router internet access and power cycle (unplug and plug back in the ATA).
Troubleshooting
| Issue | Solution |
| No power lights | Ensure the power adaptor is connected and the plug socket works |
| No dial tone | Check the phone cord is firmly plugged into Phone 1. Restart the ATA |
| No internet/network light | Make sure the ethernet cable is connected to your router. Try another port |
| Unable to make calls | Wait two or three minutes after powering up for the ATA to register. Check your internet connection |
| Poor call quality | Check for a strong internet connection. Avoid heavy network usage during calls |
