Faulty hardware Ensure that all cables and handsets used for your VoIP service are undamaged and plugged in securely.

 

The TP-Link VR1600v receives its VoIP settings automatically so you shouldn't need to check the settings during troubleshooting.
 

  1. Confirm that your handset is plugged in to the modem's Phone 1 port securely.
     
  2. Ensure that the handset used for your VoIP service has sufficient power, particularly if it is cordless and uses batteries. Only rechargeable batteries should be used in a cordless handset.
     
  3. If you still experience call dropouts on your VoIP service, please use an alternate phone service to call our Support Team on 13 22 58 for further assistance. If you don't have access to a working phone service, please email support@iinet.net.au.

 

  1. Ensure that the handset used for your VoIP service has sufficient power, particularly if it is cordless and uses batteries. Only rechargeable batteries should be used in a cordless handset.
     
  2. On a computer or WiFi device that's connected to your modem, open your web browser and go to http://10.1.1.1
     
  3. Log in with the default username admin and default password - on the TG-1, this is “admin”. On the TG-789, this is a unique password printed on the sticker on the base of the modem next to "Password".

  7. If you don’t experience VoIP call dropouts while your firewall/antivirus software is disabled, please contact the software’s Customer Support for help configuring your software settings so it won’t interfere with VoIP calls.
