Known Issues

SIP ALG is enabled by default and cannot be disabled.  It will cause intermittent one-way audio, call/fax failures, and many phone feature failures.

Resolution

Replace your router with a recommended one if you do not have one already.

• 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.
