Known Issues

1. Even with the software firewall disabled, the router still intermittently closes NAT bindings that are idle for less than 15 seconds.
   • This affects Polycom and Vertical phones the most because the NAT keep-alive packets on those phones are set to send a packet every 15 seconds to keep their connection through the firewall open.
   • Setting the NAT keep-alive on the phones to 5 seconds prevents the router from closing the phone's open connection, but it is not a permanent solution because this setting change does not persistent when the phone is rebooted. 

Temporary Resolution

1. Login to gateway
2. Go to Firewall Settings > Select No Security (None) > Save
3. Go to Advanced > Click Yes to warning > Click on ALG > uncheck SIP > Save

Permanent Resolution

1. Buy a recommended or serviceable router if you do not have one already.
2. Then you will need to call your ISP to bridge the Ubee to your compatible router.
   • UNIVERGE BLUE® cannot setup the new router for you, but your IT or the manufacturer of your new router can help you.
   • They will need to move settings from the old to the new router to ensure your computers and other devices on the network work properly.
