Troubleshooting (continued)

11. Video freezes during a call.

Far side muted their video. If the far side mutes their video you will not be able to see him or her.

Network is congested. Give the VideoPhone a couple of minutes to try to recover, or disconnect the call and try again at a later time.

12. No audio in call.

Audio cables are not plugged in correctly. Ensure that your audio cables are correctly plugged into the TV. Make sure that the TV is set for video input. Check the volume level on the TV. Consult your TV manual for reference.

Telephone is not set-up properly. Plug the telephone into the back of the VideoPhone. If the telephone is powered (cordless) make sure that it is plugged into a power supply. Consult your telephone user manual for reference.

VideoPhone is not functioning properly behind a firewall. Place the IP Address of the VideoPhone in the DMZ of the firewall. Consult your router’s documentation or your network administrator for help on doing this.

Port forward the appropriate ports to the VideoPhone. The VideoPhone needs ports 1720 (TCP) and ports 15328-15333 (TCP and UDP) open to function properly. Consult your router’s documentation or your network administrator for help on doing this.
